  • Gravity Concentration in Artisanal Gold Mining MDPI

    The selection of a concentration equipment depends on several variables, such as the mineralogy of the ore, shape of gold particles, pulp density, pulp viscosity, equipment cost, the availability of spare parts, and the grain size of the gold particles Generally, the applicability of gravity concentration equipment for different gold ores is related to the grain size of the liberated goldConcentration means increasing the amount of gold in ore or sediment, by selectively removing lighter particles If employed effectively, concentration methods can eliminate or greatly reduce the need for mercury Before concentration can begin, ore must be crushed or milled to liberate gold particles from rock and to decrease grain size Concentration works best when grainArtisanal and SmallScale Gold Mining Without Mercury | US EPAWhite,, John B Jr, "Testing and Concentration of a Low Grade Gold Ore from Marysville, Montana" (1942)Bachelors Theses and Reports, 1928 1970Paper 172 TESTING AND CONCENTRATION OF A LOW GRADE GOLD ORE FroM MARYSVILLE, MONTANA, By John B White, Jr~ A Thesis Submitted to the Department of Mineral DreSSing in PartialTesting and Concentration of a Low Grade Gold Ore from
