Water and soil pollution are critical concerns in the mining industry and can be caused by toxic heavy metals, surfactants, fine particles of minerals, oil and grease, soaps and detergents, rubber, poisonous chemicals, high acidic or alkaline chemicals, and coal particles.
Mining provides essential raw materials for an industrialized society. However, it causes serious pollution of surface and groundwater. Transferring minerals from deep below the surface to the surface promotes oxidation reactions. Oxidation of iron salts and of sulfur-containing materials in the presence of water leads to highly acidic solutions.
