The gold flotation process mainly includes four stages: dosing, agitation, aeration, and scraping. Gold flotation process is suitable for processing gold bearing sulfide ore with fine particle size and good floatability. During flotation, sulfide ore is enriched into sulfide concentrate as a carrier for gold.

Gold processing - Mining, Concentrating, Refining: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then …
