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.
