Abstract

A system of gold recovery whereby the bulk waste component of a gold ore is removed by froth flotation and the resultant concentrate is then treated by conventional cyanide leaching procedures, characterized in that 96 - 98 % of gold from the ore is finally recovered whereby the system includes the steps of: a) Crushing and grinding of the ore; b) Separating the sand from the primary slime; c) Treating said primary slime with sulfhydric collector; d) Secondary grinding of said sand, and separating the secondary slime from the sand; e) Treating said secondary slime with sulfhydric - fatty acid collector; f) Treating said sand with sulfhydric- fatty acid collector; g) Collecting the concentrates from (3), (5) and (6), and separating sand there from (at 20 -30 μ); h) Treating said concentrate with cyanide; i) Passing activated carbon countercurrent to the flow of the concentrate; j) Separating the tails and residue from the loaded carbon; k) Treating the loaded carbon with hot cyanide and caustic solution; and I) Electrowinning the liquor and smelting gold into bullions
