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.
