Gold Extraction & Recovery Processes

29/02/2016· Perhaps, one of the greatest challenges in the gold mining industry is to produce high grade concentrates consistently at maximum recovery from the mineralized deposit To quantify recovery is a reasonable idea of the initial ore required to have an economical operation In this part, a reliable sampling representing the ore is a key aspect Separation, concentration and leachingThe low concentration of gold in primary rocks means that upgrading by a factor of 30004000 is usually required during ore formation processes to achieve commercial concentrations This may be possible using natural gravity concentration processes or leaching gold with natural fluids from the host rock Thus, by highly oxidizing, acidic and complexing (chloride) solutions, followed by(PDF) Gold Extraction and Recovery Processes For Internal
