Advantages Of Using Gravity Concentration For Gold

Using gravity concentration to optimize gold recovery is now a necessity in today’s competitive mineral industry.. At Sepro, our goal is to help you squeeze out every ounce of gold from your recovery circuit. While froth flotation and cyanide leaching both play major roles in gold recovery, the benefits of using gravity concentrators cannot be understated.

Gravity concentration produced a concentrate grading from 10,263 to 62,143 g/t Au, recovering from 54–67% of the gold from the ore. Flotation produced a concentrate grading 91 to 120 g/t Au. For most of these tests, a total recovery (gravity concentration and flotation) in the order of 93% to 94% was achieved.
