Hardrock mineral exploration and extraction is dramatically different from any other natural resource. The extracted rock from metal ores contains only a minor fraction of metallic minerals, while unprocessed and excess materials are not salable. Natural …
presence of hardrock minerals (e.g. copper, nickel, platinum, palladium and others) has also been known and explored since at least 1948 (Miller 2002), and recent increases in prices and improvements in technology have spurred renewed interest in exploring for hardrock minerals.
Hardrock mining is a large-scale industrial activity that takes place in the natural environment, potentially disturbing large amounts of material and land area. Hardrock mining generates large volumes of mining waste because of the high waste-to-product ratios associated with producing most ores.
About Hardrock Mines. These are primarily ores and metals (e.g. gold, silver, copper, lead, zinc, nickel). Most are small to medium in size, though there are a handful of large, significant sites. These sites are predominately in the West, which gave rise to the establishment of cities and towns during homesteading (Westward population expansion).
The minerals on Federal lands are divided into three categories, each subject to different laws and regulations. Locatable, which are subject to the Mining Law of 1872, as amended, include gold, silver, copper and other hard rock minerals. Leasable minerals, such as coal and a host of other commodities, are subject to various Mineral Leasing Acts.

Mining of hardrock minerals on federal lands is governed primarily by the General Mining Law of 1872. The original purposes of the Mining Law were to promote mineral exploration and development on federal lands in the western United States, offer an opportunity to obtain a clear title to mines already being worked, and help settle the West. The Mining Law grants free access to individuals and ...
Hardrock mines disproportionately impact the environment, health, and culture of Native communities. Historically, mining on and near tribal lands occurred with minimal input from tribes. Beginning in 1891, Congress passed a hodge-podge of federal laws allowing mining companies to lease minerals on tribal lands--often without tribal consent.
Each mineral in the scale scratches the one below it (the lower number) but not the one above it (the higher number). This became known as Mohs' scale of hardness, and is still one of the best practical methods of estimating a mineral's hardness. Mohs designated ten minerals for his scale from hardest (10) to softest (1) (listed with objects of ...
HRA looks for resource companies with the potential to at least double over one year based on asset or reserve growth through development of metals deposits for production or take over by larger companies. HRA also uncovers high risk/high potential exploration plays, the kind of "swing for the fences" trade that can yield returns of hundreds or ...
Minerals can be classified according to their chemical composition or Moh's hardness scale, see Figure 1. Rocks are composed of assemblages of minerals. The arrangement and size of the individualgrains of these minerals give the rock an individual form or

Hard Rock: Around since the bronze age, miners over time have optimized their hard rock operations to achieve not only extremely efficient production, but also sustainable practices. Lithium found in 'hard rock' are a part of minerals hosted in Pegmatites. Pegmatites are intruding rock units which form when mineral-rich magma intrudes from ...
The hardrock mining industry is the single largest source of toxic waste and one of the most destructive industries in the country. Today's industrial-strength mining involves the blasting, excavating, and crushing of many thousands of acres of land and the use of huge quantities of toxic chemicals such as cyanide and sulfuric acid.
