Environmental Issues Environmental impacts of mining largely depend on the methods used and the geological context that governs how easily the minerals can be separated from the ore material. Unlike gold mining, which often uses potentially toxic chemicals such as mercury and cyanide, gemstone mining does not depend on chemicals for extraction ...
Many mines and mine owners these days do actively employ conservationists, just as oil companies do, to ensure that environmental impact of their activities (once they have finished mining) is kept to a minimum. quarries are filled in and grassed over, mines are levelled out and landscaped or flooded and turned into lakes and wildlife centres.
Mining is an inherently invasive process that can cause damage to a landscape in an area much larger than the mining site itself. The effects of this damage can continue years after a mine has shut down, including the addition to greenhouse gasses, death of flora and fauna, and erosion of land and habitat.

Industrial sand and gravel, often called "silica," "silica sand," and "quartz sand," includes sands and gravels with high silicon dioxide (SiO2) content. These sands are used in glassmaking; for foundry, abrasive, and hydraulic fracturing (frac) applications; and for many other industrial uses. The specifications for each use vary, but silica resources for most uses are
