Base Metal and Iron Ore Mininglution concerns in the mining industry. Removal of overburden to access the ore can pose major problems in storage and reclamation. The overburden (wastetoore) ratio for surface mining of metal ores generally ranges from 2:1 to 8:1, depending on local conditions. The ratio for solid wastes from underground mining is typically :1.
Sources of pollution: mining Sources of pollution: mining. Acidic drainage and the leaching of metals from the mine workings and mine wastes may occur at metal mines. Acidic drainage can cause significant impacts on water quality and aquatic ecosystems. Chemicals that are used to process metalbearing ores can also be found in mine waste water.
