Abstract
The process of gold desorption with LEWATIT anionites saturated in the cycle of sorption leaching of olympiadinsky flotation concentrate after bio-oxidation has been researched. Influence of temperature, alkali concentration and sodium cyanide addition in eluent on the process parameters has been researched. Optimal parameters of desorption have been founded and kinetic dependences of eluation of gold and metal additives have been formed.
keywords Gold, desorption, sorption, anionite, leaching, eluent, eluate, sodium hydroxide.
