Gravity Concentration Methods | SpringerLink

Gravity Concentration — the separation of minerals by virtue of specific gravity — is one of the oldest forms of mineral processing. Whilst its relative importance has declined in the twentieth century, the high cost of alternative processes, along with the development of a range of high capacity devices has led to something of a renaissance of gravity concentration.

Malachite

Malachite also has a specific gravity of 3.6-4.0, which is relatively heavy for a non-metallic mineral. It is also known for its effervescence in acid, which means it will bubble and fizz when exposed to acid. Malachite has been used for a variety of purposes throughout history. In ancient Egypt, it was used as a pigment for paint and cosmetics.

Processes

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.
