Spirals in Australian mineral processing
Gravity concentration is a mineral processing technique used to separate minerals based on their specific gravity or density. This is a physical separation process that uses differences in mineral density to separate them. It takes advantage of the fact that dense minerals settle faster than lighter minerals when placed in liquid or water.
