contact usMining 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.
contact usAbstract Determination of Capital Expenditure (CAPEX) is a challenging issue for mine designers. Underestimating the capital cost in mining projects may postpone the construction and accordingly the production phases. In addition, overestimating the capital cost may decrease value of the project. Currently available capital cost estimation models cannot predict mining CAPEX in a reliable range ...
