In traditional cyanide leaching ore is placed in vats or columns The cyanide solution percolates through the ore and dissolves the gold which is then removed from the lixiviant by adsorption onto carbon or resins Grain size oxygen and alkalinity levels are carefully controlled to ensure maximum gold recovery Heap LeachingCopper and cyanide recovery from barren leach solution at the gold processing plant Oscar Lopez BioteQ Water Chile SpA Santiago Chile Managing Director 562 2 896 olopez bioteqca Nebojsa Petrovic Engineering Dobersek Mönchengladbach Germany Deputy Sales Director

Solvent extraction reagents for gold recovery from Carbon and Resin Technologies for Gold Recovery sgs

Three different solvent extraction systems for the recovery of gold from alkaline cyanide solutions are reviewed These include the modified amine extractants in which the basicity of simple alkyl amines with respect to the aurocyanide anion is controlled by the addition of alkyl phosphorous esters The selectivity of such modified amines for gold extraction from alkaline cyanide solutions During this process the cyanide leaching solution passes through columns filled with ore The process is highly effective for removing gold from low grade ore Resin Recovery Technologies Resin RIL Resin in leach /RIP Resin in pulp In recent years resin is replacing carbon as the gold recovery substrate of choice SGS is the world leader
