Limestone Mining

Limestone is used extensively in Michigan to refine beet sugar. When burned in a kiln to drive off gases, calcite and dolomite form burnt lime. Among the uses for burnt lime, in addition to steel making, are water and sewage treatment, acid waste neutralization, and road base stabilization. Crushed calcite and dolomite are used in concrete ...

Environmental Risks of Mining

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.

Mine reclamation

Reclamation processes. As part of the life cycle of a surface coal mine, completed mine areas must undergo rehabilitation.When mining ends, operators must restore the land to its approximate original contour (AOC) or leave the land graded and suitable for a "higher and better" post-mining land use (PMLU) that has been approved as part of the original mining permit application.
