What Is ISL Uranium Mining

In situ leach mining (ISL), also known as in-situ mining or solution mining, was first used as a means to extract low grades of uranium from ore in underground mines. First used in Wyoming in the 1950s, originally as a low production experiment at the Lucky June mine, it became a high-production, low cost method of fulfilling Atomic Energy Commission uranium requirements at Utah Construction Company's Shirley Basin mining operations in the 1960s. Pioneered through the efforts of Charles Don Snow, a uranium mining and exploration geologist employed by Utah, many of his developments are still used today in ISL mining.

What is ISL mining? According to the Wyoming Mining Association website, ISL mining is explained in the following manner. (We choose Wyoming because it is the birthplace of "solution mining" as it was originally called.)

"In-situ mining is a noninvasive, environmentally friendly mining process involving minimal surface disturbance which extracts uranium from porous sandstone aquifers by reversing the natural processes which deposited the uranium.

To be mined in situ, the uranium deposit must occur in permeable sandstone aquifers. These sandstone aquifers provide the "plumbing system" for both the original emplacement and the recovery of the uranium. The uranium was emplaced by weakly oxidizing ground water which moved through the plumbing systems of the geologic formation. To effectively extract uranium deposited from ground water, a company must first thoroughly define this plumbing system and then designs well fields that best fit the natural hydro-geological conditions.

Detailed mapping techniques, using geophysical data from standard logging tools, have been developed by uranium companies. These innovative mapping methods define the geologic controls of the original solutions, so that these same routes can be retraced for effective in situ leaching of the ore. Once the geometry of the ore bodies is known, the locations of injection and recovery wells are planned to effectively contact the uranium. This technique has been used in several thousand wells covering hundreds of acres.

Following the installation of the well field, a leaching solution (or lixiviant), consisting of native ground water containing dissolved oxygen and carbon dioxide, is delivered to the uranium-bearing strata through the injection wells. Once in contact with the mineralization, the lixiviant oxidizes the uranium minerals, which allows the uranium to dissolve in the ground water. Production wells, located between the injection wells, intercept the pregnant lixiviant and pump it to the surface. A centralized ion-exchange facility extracts the uranium from the barren lixiviant, stripped of uranium, is regenerated with oxygen and carbon dioxide and recirculated for continued leaching. The ion exchange resin, which becomes 'loaded' with uranium, it is stripped or eluted. Once eluted, the ion exchange resin is returned to the well field facility.

During the mining process, slightly more water is produced from the ore-bearing formation than is reinjected. This net withdrawal, or 'bleed,' produces a cone of depression in the mining area, controlling fluid flow and confining it to the mining zone. The mined aquifer is surrounded, both laterally and above and below, by monitor wells which are frequently sampled to ensure that all mining fluids are retained within the mining zone. The 'bleed' also provides a chemical bleed on the aquifer to limit the buildup of species like sulfate and chloride which are affected by the leaching process. The 'bleed' water is treated for removal of uranium and radium. This treated water is then disposed of through waste water land application, or irrigation. A very small volume of radioactive sludge results; this sludge is disposed of at an NRC licensed uranium tailings facility.

The ion exchange resin is stripped of its uranium, and the resulting rich eluate is precipitated to produce a yellow cake slurry. This slurry is dewatered and dried to a final drummed uranium concentrate.

At the conclusion of the leaching process in a well field area, the same injection and production wells and surface facilities are used for restoration of the affected ground water. Ground water restoration is accomplished in three ways. First, the water in the leach zone is removed by "ground water sweep", and native ground water flows in to replace the removed contaminated water. The water which is removed is again treated to remove radionuclides and disposed of in irrigation. Second, the water which is removed is processed to purify it, typically with reverse osmosis, and the pure water is injected into the affected aquifer. This reinjection of very pure water results in a large increment of water quality improvement in a short time period. Third, the soluble metal ions which resulted from the oxidation of the ore zone are chemically immobilized by injecting a reducing chemical into the ore zone, immobilizing these constituents in situ. Ground water restoration is continued until the affected water is suit
able for its pre-mining use.

Throughout the leaching and restoration processes, a company ensures the isolation of the leach zone by careful well placement and construction. The well fields are extensively monitored to prevent the contamination of other aquifers.

Once mining is complete, the aquifer is restored by pumping fresh water through the aquifer until the ground water meets the pre-mining use.

In situ mining has several advantages over conventional mining. First, the environmental impact is minimal, as the affected water is restored at the conclusion of mining. Second, it is lower cost, allowing Wyoming's low grade deposits to compete globally with the very high grade deposits of Canada. Finally the method is safe and proven, resulting in minimal employee exposure to health risks."

ISL mining may be the wave of the future of U.S. uranium mining, or it may become an interim mining measure, in areas where the geology is appropriate for IS. Until sufficient quantities of uranium are required by U.S. utilities to fuel the country's demand for nuclear energy, ISL mining may remain the leading uranium mining method in the United States. At some point, an overwhelming need for uranium for the nuclear fuel cycle may again put ISL mining in the backseat, and uranium miners may return to conventional mining methods, such as open pit mining.

Metallurgist Roles in Mining Companies

Mining of metals and minerals is a growth industry, especially in Africa, providing job opportunities for metallurgists to work in various roles. Positions are well paid as metallurgists are required to have at least one degree from an accredited university or college. The preferred qualifications are a Bachelors Degree in Extractive Metallurgy or Metallurgical Engineering or BSc. in Chemical Engineering with a major in Mineral Processing. This is not a profession where candidates can learn the required skills on the job although experience can be gained throughout their career by expanding their exposure to different types of work on mines.

The type of work they do

The most common metallurgist roles include project management, consulting, technical or site management and research. For example, on a mine he/she would be expected to:

•    Design work programs and manage all metallurgical testing both in-house and with external service providers and laboratories

•    Work with the senior team to review and evaluate technical solutions

•    Liaise with geologists and other technical personnel to ensure the most suitable metallurgical solution is understood and employed

•    Constantly re-evaluate the metallurgical performance

At middle management level, as a project manager they would coordinate day-to-day mining activities, manage quality assurance and generally ensure a smooth operation. Mining companies look for a minimum of 5 years experience before they post these types of managers to remotely located mines. At the most senior level metallurgists can become mine managers which includes coordinating all operations, staffing, running the site itself, selecting the extraction process, and resolving operational and business issues.

Furthering a career

Metallurgists with further education and extensive experience in many technical processes become professional consultants or researchers either working directly for a large mining company or for a consulting firm contracted to it. Their role may be to advise clients on process engineering, to perform cost analyses or do budgeting. They may get involved in environmental impact assessments, HSEQ and social responsibility as well. The mining industry is constantly updating its methods of extraction and waste management in order to stay profitable and needs researchers to continue to explore new methods and processes. Pay levels vary depending on work experience, area of expertise and the location where they are posted.

Some of the personal attributes required to be successful in this field are to be an effective team player, have a high level of inter-personal communication skills and be able to express yourself in writing. A good knowledge of French is often asked for when an African posting is offered. Because of inhospitable locations and remoteness of mines, most of the postings attract single people or more mature staff who do not have school-going children.

Coal Mining: Timeless Black Gems

Coal is an abundant sedimentary rock and fossil fuel used primarily as an energy source for electricity and other industrial uses such as smelting and alloy production. Coal is seldom confused with charcoal, which is primarily of wooden origin. Coal was previously used as mere household heating commodities but when the industrial revolution began, coal mining started to became large-scale. It then became an important commodity to produce electricity as well as to provide primary energy for industries as well as transportation during the 18th century to the 1950s.

Coal mining can be a very dangerous activity most especially when it involves mining underground. Gases produced can be very toxic or highly flammable, capable of explosions which can instantly kill a team of miners. Fortunately, technology has enabled companies the capacity to effectively protect their workers from the hazards of coal mining. But not only that, they can also do the same or even higher output even with significantly less number or workers.

Coal mining can involve mining underground by shaft mining or, for a more accessible and easier way, open pit mining the rock strata coal beds or coal seams. However, there are several other ways in coal mining.

Coals near the surface can be extracted by using open cut mining methods. Explosives are first used to break through the surface of the mining area and after which it is removed by draglines or by shovel and a truck. With the coal seam exposed, drills are utilized to fracture and thoroughly mine it in strips. Area mining involves drilling holes against the surface of the mining area and then planting the drill holes with explosives. When the surface is exposed, there will be a coal seam exposed. This can be extracted, mined and transported with trucks immediately. If it is still hard enough, this can also be drilled and blasted with explosives. The coal can then be collected until there is none left in the strip - then the process can be repeated to create a new mining strip. This coal mining method is most ideal for flat terrain.

One particular coal mining method is controversial. This is the mountaintop removal mining - and just as its name says, it's literally removing the mountain top, making the ridges and hill tops look like flattened plateaus. It is controversial because it drastically alters the topography as well as disturbing the ecosystem. Valleys will be filled the extracted prize and streams will be covered. The objective to coal mining was to extract these valuable energy sources, but is it really worth the damaging the environment or even risk worse consequences?

Online Retail - Mining for Gold

Online retailers live in an ever-changing environment, and the ability to stay competitive is the difference between doing well and doing nothing. In today's fast paced internet market place, if you aren't using web scraping, you are missing a key component to growing your business.

Data Mining

Data mining your competition's prices and services and making sure your prices and services are similar, or even lower, is what makes the difference. Why should your customer choose you if they can get the same product somewhere else for less? What data you collect and how often you update it is also another key ingredient to success.

Extract Website Data

Web scraping allows you to gather information from your competition and use it improve your position in the market. When you extract website data from your competitor's website, it allows you to conduct business from a position that doesn't involve guess work. The internet is an environment that is constantly being updated and changed. It is vital that you have the ability to have up-to-date information on what others in your market are doing. If you can't do this, you really can't compete.

Application of Information

When you know what your competitors are doing all the time, you can keep your business a little more competitive than they are. When you have information such as monthly and even weekly price variations in the market and what products and services are being offered, you can apply that information to your own pricing matrix and ensure a competitive edge in your market.

An Army of One

Web scraping gives you the ability to see what is going on in the market at all times. You can monitor just about anything you choose with a web scraping service. Many online retailers are very small operations and they don't have the resources to constantly monitor each competitor's website - so engaging a web scraping service is like having your own marketing and research team working for you night and day to keep tabs on them. You choose what it is you want to know, and your research team goes to work. Simple.

Staying Ahead of Trends

Having the ability to recognize trends is the key to any business, especially on the internet were information is so fluid. The business that can identify a trend quickly and take advantage of it will always stay one step ahead. That's why big corporations have teams dedicated to researching market trends and predictions. If you can see where something is going, you can always get ahead of it. That's what web scraping can help you do - identify those trends in your market so you can get in ahead of the pack.

A Helping Hand

Sometimes running your own online retail business can be a daunting and lonely ordeal. Even those that have a great deal of experience with the internet can feel lost at times. A web scraping service is a tool you can use to help yourself in such times. Web scraping is automated and precise, and it gives you the ability to have vital information delivered to you in a manner you can understand and use. It's one less thing to worry about - and the information you get from data mining is what every business owner actually should worry about - what the competition is doing? With a web scraping service, you can concern yourself with other things - like making more profits.

There is No Need to Disrupt the Schedule to Keep the Kitchen Canopy and Extraction System Clean

After taking over a large and beautiful stately hotel its new owner quickly realised that the kitchen extract system would not be straightforward to maintain because the duct work for the extract system was somewhat ancient and therefore would be difficult to clean.

A prestige hotel needs to maintain a high level of hygiene as well as to minimise the risk of a kitchen fire.

So, if replacing the entire system is not an option what can the new owner do to find a solution that would meet exacting standards of cleanliness and ensure that the risk of a fire starting in the system is minimised while ensuring that the cleaning does disrupt the operation of the hotel and restaurant as a business?

Using an experienced specialist commercial cleaning service to asses the establishment, the types of food cooked, how and at what level of intensity is the first step.

It is difficult without this information to advice on how maintenance should be carried out.

The frequency of the cleaning cycle for a canopy and its components depends not only on the regularity and duration of cooking below but also on the type of cooking and the ingredients being used.

Where  the kitchen use is light canopies and extract systems may only need a 12-month cycle for maintenance and cleaning. However, in a busy hotel, kitchen activity is most likely to be heavy and the cleaning company may advise a three or four-month cycle.

Grease filters and canopies over the cookers should ideally be designed, sized and constructed to be robust enough for regular washing in a commercial dishwasher, which is the most thorough and efficient method of cleaning them yourself.

It's important to make sure when re-installing filters that they are fitted the right way around with any framework drain holes at the lowest, front edge. Of course, grease filters are covered with a coating of grease and can therefore be slippery and difficult to handle. Appropriate protyective gloves should be used when handling them.

The canopies and their component parts should be designed to be easy to clean, but if they are not, provided the cleaning intervals are fairly frequent, regular washing with soap or mild detergent and warm water, followed by a clean water rinse might be adequate. If too long a period is left between cleans, grease will become baked-on and require special attention.

No grease filtration is 100% efficient and therefore a certain amount of grease passes through the filters to be deposited on the internal surfaces of the filter housings and ductwork.

Left unattended, this layer of grease on the non-visible surfaces of the canopy creates both hygiene and fire risks.

Deciding on when cleaning should take place, and how often, is something an experienced specialist cleaning company can help with. The simplest guide is that if a surface or component looks dirty, then it needs cleaning.

Most important, however, is regular inspection of all surfaces and especially non-visible ones. The maintenance schedule for any kitchen installation should include inspections.

A regular maintenance and cleaning schedule is not impossible even in the kitchen of a hotel with an antiquated canopy and duct system with the help of a specialist commercial cleaning company to advise on how to do it without disrupting the work flow, as writer Ali Withers discovers.

Websites Can Contractually Restrict Third Party Scraping of Their Data

E-commerce service providers can contractually prevent other websites from copying factual information from their website for commercial use, such as for price comparison purposes.

On 15 January 2015, the Court of Justice of the European Union (CJEU) confirmed in a preliminary ruling that websites not protected by a database right, are free to impose contractual restrictions on the use of their data. Interestingly, the CJEU acknowledged that the contractual restrictions could – if national law permits - be imposed through the website’s terms and conditions.

Let’s have a quick look at how this matter arose. Since the early days of online reservations, some websites discovered that they could attract a lot of visitors by comparing the online prices displayed by e-commerce websites selling competing goods and services. Originally such third party websites were called “content aggregators” and today one particular type, so-called “price comparison” websites, is widely-known.  To be able to aggregate such content and create added-value for the consumer, these websites use automated software that visits the e-commerce websites and copies the latter’s pricing information in real time. This practice is often referred to as “screen scraping” and frequently occurs in the online travel reservation business. Some of these third party websites do not only show the compared prices of airline tickets but act as an intermediary for booking travel packages, including car and hotel rental services on top of the airline ticket, often after adding a commission.

In response, low-cost airlines quickly started taking legal action against such screen scraping practices, fearing the loss of such additional, revenue-generating services to these third party websites and also through suffering reputational damage when consumers were not properly informed about issues such as flight changes and cancellations. In these circumstances there was one case between the low-cost airline, Ryanair, and the third party website owner, PR Aviation BV, in which the Dutch Supreme Court made a preliminary ruling request to the CJEU.

The CJEU, in its preliminary ruling on the scope of database protection and contractual freedom, ruled in Ryanair’s favour. It concluded that, in the absence of any database related copyright or sui generis protection on Ryanair’s website, Ryanair was expressly allowed to lay down contractual limitations on the use of its website by third parties. Ryanair would not have had such contractual freedom if its database enjoyed copyright or sui generis database protection (due to the restriction laid down in Article 15 of the Database Directive 96/9/EC). Ryanair’s terms and conditions, to which users had to visibly agree when searching for flights (but without needing to explicitly tick a box), indeed stated that the use of any automated system or software to extract data from its website for commercial purposes was prohibited. Ryanair even went as far as to explicitly state that other websites could not sell its flights and that price comparison websites had to enter into a written licence agreement with Ryanair,
to access Ryanair’s price, flight and timetable information for the sole purpose of price comparison.

As a consequence of the CJEU’s ruling, any website making available mere factual information not protected by any legal right, can still prevent others from using such information through its terms and conditions. Clearly, that website will have to demonstrate under applicable (national) law that the website visitor is contractually bound, in particular because it validly agreed to such terms and conditions. Depending on the applicable law, such agreement by the consumer could be considered as having taken place by ticking a box or merely after having been made aware of the website’s terms and conditions.

The CJEU’s ruling is likely to impact upon the business model of a number of content aggregating/price comparison websites. The ruling’s concrete relevance, however, will have to be assessed on a case-by-case basis.
