Both surface and underground mining often require large quantities of rock to be broken away to reach the ore. Gangue is usually placed in heaps near the mine. This seepage is called acid mine drainage. How can mining become more environmentally sustainable. Environmental impacts and legacies of iron mining in Industrial Revolution landscapes of the United States varied in extent and in- tensity according to the type of mining methods used—quarry, shaft, or open-pit mining—and the specific geological character of the min- ing region, especially the elemental composition of iron-bearing ore deposits. What follows are the typical phases of a proposed mining project. Megafauna includes large mammals such as black bears, caribou, and wolves. [7] Wetlands serve a number of functional purposes in the biosphere such as collecting and storing surface runoff, moderating stream flows, reducing natural flooding and erosion, cleaning and purifying water, recharging groundwater zones, and providing habitats for plants and animals,. When sulfides in the ore are exposed to water and air, sulfuric acid is created, which can seep from mines and waste rock piles into streams, rivers, and groundwater. For example, acid drainage and high metal concentrations in rivers generally result in an impoverished Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.
