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.

Mining

Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit.These deposits form a mineralized commodity that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.

Common & Basic Formulas for Mineral Processing Calculations

 · The value of the products actually made in the laboratory test or in the mill is calculated simply by liquidating the concentrates according to the smelter schedules which apply, using current metal prices, deduction, freight expense, etc., and reducing these figures to value per ton of crude ore by means of the ratios of concentration.
