Increase Gold recovery in Copper flotation Froth
If the gold is combined with the copper than if your current grade is 0.8 g/t (grade), to raise this you need to reduce the overall recovery, and lose copper. If the gold is separate than you need to adjust the scavenger and re-cleaner circuits to get more recovery of the gold by adjusting the reagents. (Note you may lose copper doing this also).Gold flotation,Gold processing,Gold ore processing,③ The relative density of gold is very large. In the process of flotation, the gold particles are easy to fall off from the bubble surface after contact with the bubbles. ④ In oxidized ores, the surface of gold particles is often contaminated or covered by iron oxides.
