Cheap Leach With Ore Processing Plant

An Introduction Metallurgical and Processing Solutions

In a typical application a slurry of the ground ore is mixed with cyanide in the presence of activated carbon The carbon has a very high affinity for the aurocyanide complex and adsorbs the gold out of solution resulting in very high loadings on the carbon typically 1000 4000 g/t At the end of the leach the loaded carbon is removed from the slurry and the adsorbed gold is stripped out at

Recovery of PGMs from an oxide ore by flotation and leaching

PGM concentrator plants achieve high PGM recoveries >85% when treating prestine unweathered sulphide ores However the depletion of prestine sulphide PGM bearing minerals has triggered interest in exploration of techniques for PGM recovery from near surface oxidised PGM ores All earlier attempts to process the oxidised PGM ores by conventional flotation methods achieved poor recoveries
