Gold Ore Beneficiation Plant
Gold plays important role in human’s life. Gold occurs principally as a native metal, usually alloyed to a greater or lesser extent with silver (as electrum), or sometimes with mercury (as an amalgam). Native gold can occur as sizeable nuggets, as fine grains or flakes in alluvial deposits, or as grains or microscopic particles embedded in other rocks.
Ores in which gold occurs in chemical composition with other elements are comparatively rare.
They include calaverite,sylvanite, nagyagite, petzite and krennerite.
Gold ore beneficiation is a processing to get gold out of ores.
gold in the mineral is extremely low, in order to extract the gold, ore crushing and grinding is needed and using dressing method to separate gold from the gold ore. gravity separation and flotation separation is mainly methods in gold ore beneficiation plant. gravity separation occupies an important position in gold production. flotation separation is widely used in rock gold mining beneficiation. currently about 80% of the rock gold mine use this method for ore beneficiation. According to Gold ore characteristics and gangue content, different techniques could be used in beneficiation process.
First, uniform fine particle sizes are produced through the crushing and grinding process. And then magnetic separation is most commonly used to separate natural magnetic Gold ore from various less-magnetic or nonmagnetic materials. Sometimes, gravity or flotation method maybe used instead of magnetic separation. In the end, thickening and dewatering are used to remove the moisture or liquid from slurries concentrates and waste slurries. Through all these processes, the concentrated ore are separated from unwanted gangue.
There are various types of equipment involves in the Gold ore beneficiation process, such as jaw crusher, impact crusher, cone crusher, ball mill, high pressure mill, sand washing machine, vibrating screen and feeder, filtering machine, gravity separator, magnetic separator, flotation separator, thickener, dryer, belt conveyor etc.
