 | A University of Arizona College of Engineering research program looking at new methods of determining rock strength could reduce hazardous working conditions that currently cause thousands of deaths every year in mining and construction. ...> Full Article |
Increased salinity and concentrations of trace elements in one West Virginia watershed have been tied directly to multiple surface coal mines upstream by a detailed new survey of stream chemistry. The Duke University team that conducted the study said it provides new evidence of the cumulative effects multiple mountaintop mining permits can have in a river network.

China sent the high-tech industry and markets reeling when it blocked exports of raw rare earth minerals. The sudden severing of rare earths supply was a frightening prospect as the minerals are key ingredients in high-tech products. Governments around the world saw the ban as a kind of wake-up call and started looking at ways to develop their own mineral resources -- for rare earths as well as basic industry metals like copper and zinc.

Thanks to computational advances over the last decade, McGill Professor Roussos Dimitrakopoulos, has developed new mathematical modeling techniques for mine planning that take into account uncertainty in the supply of minerals. The result of this research has been both a much higher return on investment for the mining companies but also more metal production from the same asset.

 | A team of University of Nevada, Reno, and University of Nevada, Las Vegas, researchers have devised a new model for how Nevada's gold deposits formed, which may help in exploration efforts for new gold deposits. ...> Full Article |
Collaborating with an international research team, an economic geologist from The University of Western Ontario has discovered how gold-rich magma is produced, unveiling an all-important step in the formation of gold mines. Robert Linnen, of Western's Department of Earth Sciences found sulphur enhances gold's solubility, and solubility is an important step in forming a gold deposit. The study, published in Nature Geoscience, could lead to a breakthrough in choosing geographic targets for gold exploration.

 | As the US Environmental Protection Agency weighs whether to define coal ash as hazardous waste, a Duke University study identifies new monitoring protocols and insights that can help investigators more accurately measure and predict the ecological impacts of coal ash contaminants. ...> Full Article |
Approximately 13 million metric tons of rare earth elements (REE) exist within known deposits in the United States, according to the first-ever nationwide estimate of these elements by the US Geological Survey.

 | A new technology for removing water from ultrafine coal slurry has been successfully tested at the commercial scale at an operating coal cleaning plant. The technology offers the possibility of reducing the coal slurry impoundment problem from the source. ...> Full Article |
New study shows that oilsands mining and processing are polluting the Athabasca River with metals that are toxic at trace levels.

 | While prospectors and geologists have been successful in finding diamonds through diligent searching, one University of Houston professor and his team's work could help improve the odds by focusing future searches in particular areas. Kevin Burke, professor of geology and tectonics at UH, and his fellow researchers describe these findings in a paper titled "Diamonds Sampled by Plumes from the Core-Mantle Boundary," appearing July 15 in Nature, the weekly scientific research journal. ...> Full Article |
 | The mining industry has stepped up its long-term support with a $2.4 million boost to the University of Nevada, Reno's mining engineering program and research; and instructors, students and administrators are pleased with the resulting real-world applications that come with a strengthened program. ...> Full Article |
 | In 2009, Peru was the world's leading producer of silver, the second leading producer of copper, and the leading producer of gold in Latin America. But this isn't something new. Peru's leadership in mining and metallurgy extends for centuries into the past. This Special Paper from the Geological Society of America documents the use in ancient Peru of minerals, metals, and mineral resources for pigments, industrial stone, aesthetics and art. ...> Full Article |
 | The world's largest antimony mine has become the world's largest laboratory for studying the environmental consequences of escaped antimony -- an element whose environmental and biological properties are still largely a mystery. Scientists have found the waters around Xikuangshan mine in southwest China contain antimony at levels two to four orders of magnitude higher than normal (0.33-11.4 parts per million). ...> Full Article |
The value of US mineral production significantly declined in 2009. Also over the past year, US dependence on foreign sources for minerals has increased, continuing a trend that has been evident for more than 30 years. This is according to the US Geological Survey report "Mineral Commodity Summaries 2010."

 | Scientists are working on a new range of materials characterization analyzers and techniques that could help unlock the value contained in Australia's mineral deposits and improve processing performance, according to the October issue of Process. ...> Full Article |
Worldwide, thousands of workers die every year from mining accidents, and instantaneous coal outbursts in underground mines are among the major killers. But although scientists have been investigating coal outbursts for more than 150 years, the precise mechanism is still unknown.

 | CSIRO and a consortium of Australian Opal miners have unveiled the world's first automated device to grade opals using image analysis, at the 2009 National Council of Jewelery Valuers forum in Sydney. ...> Full Article |
 | Mine shafts on the point of being closed down could be used to provide geothermal energy to local towns. This is the conclusion of two engineers from the University of Oviedo, whose research is being published this month in the journal Renewable Energy. The method they have developed makes it possible to estimate the amount of heat that a tunnel could potentially provide. ...> Full Article |
