### Gravity Concentration | Gekko

Gravity concentration separates minerals based on differences in specific gravity. Specific gravity is the weight of the same volume of material compared to water, where the specific gravity of water equals 1. The specific gravity of gold is 19.3, so it is 19.3 times as dense as water.Онлайн-запрос

### Gold Gravity Concentration Mineral Processing & Metallurgy

The object of gravity concentration is the separation of the heavy valuable mineral from the light worthless gangue. Complications are often introduced by the fact that various base minerals must be separated from one another, an ore being subdivided into several products. Most gold ores, however, only require separation into two parts—the “concentrates,” in which the precious metal isОнлайн-запрос
