Gold Gravity Concentration

The object of gravity concentration is the separation of the heavy valuable mineral from the light worthless gangue. Complications are often introduced by the fact that various base minerals must be separated from one another, an ore being subdivided into several products. Most gold ores, however, only require separation into two parts—the “concentrates,” in which the precious metal is,How gravity concentration recovers ultra-fine particles,These ultra-fine particles typically make flotation unattractive and we are left with gravity concentration as the only viable option.

Mineral processing - Wikipedia

Mineral processing can involve four general types of unit operation: comminution – particle size reduction; sizing – separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering – solid/liquid separation. In all of these processes, the most important considerations are the economics of the processes and this is dictated by the grade and recovery of the final product. To do this, the mineralogy of the ore needs to be considered as this dictates the amount of liberation required and the processes that can occur. The smalle…concentrator and MGS are discussed. -Motley Vanner,,NML on beneficiation of tungsten ore and processing of iron and chromite ore slimes using gravity concentration techniques.

Finding the Ore Liberation Size For Gravity Circuits,

Tune the grinding circuit to only grind fine enough to attain the commercially-viable liberation size. If gold is found in the 200-300 or <325 mesh fractions, it is likely gold-bearing sulfides or free milling gold <~400 mesh. This gold is not practical to recover via gravity concentration, so flotation or leaching could be used.
