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.

The Equipment Used in Mining

Bureau of Labor statistics reported that there are five major segments in the mining industry. They are gas and oil extracting, coal mining, non-metal mineral mining, metal ore mining and the supporting activities. In this matter, each segment might need different equipment. But, there are some types of mining equipment that are used by all segments of the mining industry.

Excavators

Excavators are types of equipment that are used by the miners to break and remove soil today. Traditionally, they used steam shovels and shovels to do the jobs. An excavator is a vehicle that moves with standard wheels or moves on tracks. There is a rotating platform and a bucket to its end for digging the soil.

Draglines

Draglines are very big earth moving machines that are used in mining industry. These machines are used to expose the underlying mineral deposits. These are also used to drag away the dirt. The Kentucky Coal Education said that draglines are one of the largest machine in the world. These can remove several hundred tons of the material in one pass.

Drills

Drills are very important for miners that extract natural gas and oil. Miners use these machines to reach underground deposits before they pipe the resources to the surface. Instead of being used in gas and oil mining, these machines are also used to mine coal and mineral.

Roof bolters

These machines are used to prevent underground collapses when the mining process is in progress. These are also used to support the tunnel roofs in mining location.

Continuous miners and longwall miners

These machines are usually used by subterranean coal miners. These machines are used to scrape coal from the coal beds. Meanwhile, the longwall miners are machines that are used to remove large, rectangular sections of coal instead of scraping coal from a bed.

Rock duster

These are pressurized pieces of equipment that are used in coal mining to spray inert mineral dust over the highly flammable coal dust. This inert dust will help prevent accidental explosions and fires.

Coal Seam Gas - Extraction and Processing

With rapidly depleting natural resources, people around the globe are looking for new sources of energy. Lots of people don't think much of it, but doing this is an excellent ecological move forward and may even be a lucrative endeavour. Australia has one the most significant deposits of a recently discovered gas known as coal seam gas. The deposit present in areas such as New South Wales is far more significant than the others since it contains little methane and much more carbon dioxide.

What is coal seam gas?

Coal bed methane is the more general term for this substance. It is a form of natural gas taken from substantial coal beds. The existence of this material usually spelled hazard for many sites. This stopped in recent decades, when specialists discovered its potential as an energy source. It's now among the most important sources of energy in a number of countries, particularly in North America. Extraction within australia is actually rapidly developing because of rich deposits in various parts of the country.

Extraction

The extraction procedure is reasonably challenging. It calls for heavy drilling, water pumping, and tubing. Though there are a variety of different processes, pipeline construction(an initial step) is perhaps one of the most important. The foundation of the course of action can spell a real difference between the failure or success of your undertaking.

Working with a Contractor

Pipeline construction and design is serious business. Seasoned contractors may be hard to get considering the fact that Australia's coal seam gas industry is still fairly young. You'll find only a limited number of completed and working projects across the country. There are several things to consider when getting a contractor for the project.

Find one with substantial experience within the industry sector. Some service providers have operations outside the country, especially in Canada And America. This is something you should look out for, as advancement of the gas originated there. Providers with completed projects in the said area can have the solutions required for any project to take off.

The construction process involves several basic steps. It is important the service provider you work with addresses all of your needs. Below are a few of the important supplementary services to look for.

- Pipeline design, production, and installation

- Custom ploughing (to achieve specialized trenching requirements)

- Protection and repair of pipelines with the use of various liners

- Pressure assessment and commissioning

These are only the fundamentals of pipeline construction. Sourcing coal seam gas involves many others. Do thorough research to ensure the service provider you employ is capable of completing all the necessary tasks. Other elements of the undertaking include engineering plus site preparation and rehabilitation. This industrial sector may be profitable if one makes all of the proper moves.

Avoid making uninformed decisions by doing as much research as you possibly can. Use the web to your advantage to look into a company's profile. Look for a portfolio of the projects they have completed in the past. You can gauge their trustworthiness based on their volume of clients. Check out the scope of their operations and the projects they finished.

You should also think about company policies concerning the quality of their work, safety and health, along with their policies concerning communities and the environment. These are seemingly minute but important details when searching for a contractor for pipeline construction projects.

Why Common Measures Taken To Prevent Scraping Aren't Effective

Bots became more powerful in 2014. As the war continues, let’s take a closer look at why common strategies to prevent scraping didn’t pay off.

With the market for online businesses expanding rapidly, the development teams behind these online portals are under great amounts of pressure to keep up in the race. Scalability, availability and responsiveness are some of the commonly faced problems for a growing online business portal. As the value of content is increasing, content theft has become an increasing problem in the form of web scraping.

Competitors have learned to stay ahead of the race by using bots to scrape. While how these bots could be harmful is something worth talking about, it is not the main scope of this article. This article discusses some of the commonly used weapons to fight bots and brings to light their effectiveness in reality.

We come across many developers who claim to have taken measures to prevent their sites from being scraped. A common belief is that these below listed techniques reduce scraping activities significantly on a website. While some of these methods could actually work in concept, we were interested to explore how effective they were in practice.

Most Commonly used techniques to Prevent Scraping:

•    Setting up robots.txt – Surprisingly, this technique is used against malicious bots! Why this wouldn’t work is pretty straight forward – robots.txt is an agreement between websites and search engine bots to prevent search engine bots from accessing sensitive information. No malicious bot (or the scraper behind it) in it’s right mind would obey robots.txt. This is the most ineffective method to prevent scraping.

•    Filtering requests by User agent – The user agent string of a client is set by the client itself. One method is to obtain this from the HTTP header of a request. This way, a request can be filtered even before the content is served to the request. We observed that very few bots (approximately less than 10%), used the default user agent string which belonged to a scraping tool or was an empty string. Once their requests to the website were filtered based on the user agent, it didn’t take too long for scrapers to realize this and change their user agent to that of any well known browser. This method merely stops new bots written by inexperienced scrapers for a few hours.

•    Blacklisting the IP address – Seeking out to an IP blacklisting service is much easier than having to perform the hectic process of capturing more metrics from page requests and analyzing server logs. There are plenty of third party services which maintain a database of blacklisted IPs. In our hunt for a suitable blacklisting service, we found that using a third party DNSBL/RBL service was not effective as these services blacklisted only email spambot servers and were not effective in preventing scraping bots. Less than 2% of scraping bots were detected for one of our customer’s when we did a trial run.

•    Throwing CAPTCHA – A very well know practice to stop bots is to throw CAPTCHA on pages with sensitive content. Although effective against bots, CAPTCHA is thrown to all clients requesting the web page irrespective of whether it is a human or a bot. This method often antagonizes users and hence reduces traffic to the website. Some more insights to the new NO CAPTCHA Re-CAPTCHA by Google can be found in our previous blog post.

•    Honey pot or Honey trap – Honey pots are a brilliant trap mechanism to capture new bots (scrapers who are not well versed with structure of every page) on the website. But, this approach poses a lesser known threat of reducing the page rank on search engines. Here’s why – Search engine bots visit these links and might get trapped accidentally. Even if exceptions to the page were made by disallowing a set of known user agents, the links to the traps might be indexed by a search engine bot. These links are interpreted as dead, irrelevant or fake links by search engines. With more such traps, the ranking of the website decreases considerably. Furthermore, filtering requests based on user agent can exploited as discussed above. In short, honey pots are risky business which must be handled very carefully.

To summarize, these prevention strategies listed are either weak or require constant monitoring and regular maintenance to keep them effective. In practice bots are far more challenging than they actually seem to be.

What to expect in 2015?

With increasing need for scraping, the number of scraping tools and expert scrapers are also increasing which simply means bots are going to be an increasing problem. In fact, the usage of headless browsers i.e, browser like bots which are used to scrape are increasing and scrapers are no longer relying on wget, curl and html parsers. Preventing malicious bots from stealing content without actually disturbing the genuine traffic from humans and search engine bots is just going get harder. By the end of the year, we could infer from our database that almost half of an average website’s traffic is caused by bots. And a whopping 30-40% is caused by malicious bots. We believe this is only going to increase if we do not step up to take action!

p.s. If you think you are facing similar problems, why not request for more information? Also, if you do not have the time or bandwidth for taking such actions, scraping prevention and stopping malicious bots is something we provide as a service. How about a free trial?

Living Your Dream Life When Others Are Scraping Their Windshields

One Internet marketer once remarked that he knew he was successful when he was awakened one early winter morning by the sound of his neighbors scraping the ice off of their windshields so that they could drive to work. As he burrowed deeper under his covers, he grinned to himself and realized that while he wasn't sipping cocktails aboard his own yacht yet, he had reached an enviable measure of success. If you're ready to begin living your dream life, then you're ready to become an Internet marketer.

What does living your dream life mean to you? Does it mean being able to be your own boss and not having to adhere to another's schedule? Does living your dream life mean taking vacations to exotic locations? The beauty of Internet marketing is that you can realize your goals and live the life you choose. You can do all the things you've dreamed of doing and go to the places you've dreamed of seeing. You answer to no one but yourself, although most Internet marketers learn that they still have a boss even after they quit their jobs. That new boss, actually bosses, are your customers and you'll have to do a great job in order to get them and keep them.

Most Internet marketers, the ones who truly have an entrepreneurial spirit, are naturals when it comes to pleasing customers. They want to earn their business, they care about their needs and their likes and dislikes and will go out on a limb to satisfy their customers. While customer service is severely lacking in many of today's businesses, without it, you'll be dead in the water before you even get started. If living your dream life is important to you, plan now to offer the kind of customer service that no one else can rival.

Imagine living your dream life for the rest of your life. Imagine being able to take your family to the kinds of places you've only seen in movies and read about in books. Imagine having money in the bank to tide you over when times are tough and having the peace of mind of knowing that your home is not at risk. You can have all of this and more if you are willing to work hard. The rewards for Internet marketers aren't instant, but they are sweet and they can be yours.
