Advantages Of Using Gravity Concentration For Gold Recovery

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.

Gold extraction

Gravity concentration has been historically the most important way of extracting the native metal using pans or washing tables Amalgamation with mercury was used to enhance recovery often by adding it directly to the riffle tables and mercury is still widely used in small diggings across the world However froth flotation processes may also be used to concentrate the gold.
