Method #2: Gold flotation process. Flotation is a widely used beneficiation method for rock gold ore. The flotation process can maximize gold enrichment into sulfide minerals, tailings can be directly discarded, and the beneficiation cost is low. The gold flotation process mainly includes four stages: dosing, agitation, aeration, and scraping.
