New Reagent For Fine Gold Recovery During Copper Ores

During flotation treatment of copper ores, more than 30 of the metallurgical losses could be attributed to the non-recoverable fine dispersed gold. Gold particles are most commonly met in region 1-3 m. Due to their high surface hydrophobicity they are often lost in the clarified water of the thickeners. Closed loop water use does not lead to elimination of these losses.
