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.
Antimony Mining. Antimony (Sb) is a hard, brittle, silver-white metal with a relatively high specific gravity (6.69) and a relatively low melting temperature. Antimony is a constituent in some alloys. The presence of this metal hardens the alloy, lowers the melting point,
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.

There are thousands of old hard rock mines and prospects throughout Utah that produced some gold as byproducts of silver, lead, zinc, etc. Creeks and rivers near these mines always have potential to produce some gold for a placer miner, but many have had little reported about
The least common method in hard-rock mining, block caving, is typically saved for low-grade ore. It involves drilling a section of ore at the very bottom of the deposit and then blasting to make the roof collapse. Gravity then takes over, as the ore above the blast site fractures and collapses in succession as support is withdrawn.
