Base Metal and Iron Ore Mining
lution concerns in the mining industry. Removal of overburden to access the ore can pose major problems in storage and reclamation. The over-burden (waste-to-ore) ratio for surface mining of metal ores generally ranges from 2:1 to 8:1, de-pending on local conditions. The ratio for solid wastes from underground mining is typically 0.2:1.
