Heap leaching: This process uses a liquid to dissolve a chemical. Similar to the way pouring hot water over crushed coffee beans leaves coffee grounds (waste) and liquid coffee, spraying chemicals over piles of uraniumcontaining crushed rock leaves the leftover rock and a liquid containing uranium. The liquid then needs further processing to recover the uranium. This processing

In response, mining engineers have developed clever ways of waste management, making the mining industry one of the few that actively recycle their own waste. Overburden is used for reprocessing, contouring land, and as a construction aggregate for buildings and roads. Mine tailings are reused for producing clay, tiles, glass, and concrete.

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 sulfurcontaining materials in the presence of water leads to highly acidic solutions. Toxic substances are brought to the
