Gold processing | Britannica

Endogenetic deposits frequently contain elemental gold that is highly disseminated within a base metal sulfide mineral. These deposits are mined, crushed and ground, and then concentrated first by gravity separation to recover coarse particles of native gold before being subjected to froth flotation to concentrate the sulfide.
