Mined gold-bearing ore containing gold and silver is extracted and purified through a processing plant. In this gold recovery plant, the precious metals are extracted from the ore through a series of steps including: crushing and grinding; addition of process water (forming a slurry); cyanide leaching; floatation and vortex separation (cyclones).
Other ore the gold will be harder to recover, and may or may not need some type of pretreatment, floatation of sulfide ore, for example, roasting may or may not improve an ore before a recovery process, determining a leach will depend much on the composition of the ore.
