A Simple Recipe Guide to Gravity Concentration
Gravity concentration as a mineral processing technique was well established on a large scale by the first century AD Romans during the hydraulic gold mining of the mountains in north-western Spain. Gravity concentration has diminished as a first-choice beneficiation process in favour of flotation, magnetic separation and hydrometallurgy, and this has resulted in an industry loss of …

Gravity Concentration
Gravity concentration is the process in which separation is realized by using the differences in density of mineral particles in a certain medium or medium flow (mostly water). It is mostly used for separation of the ore in which the useful mineral has major density difference from the gangue, e.g., tungsten ore, tin ore, and alluvial gold ore.
