Placer gold ore dressing is generally divided into break down, screening, desliming and dressing process. Many placer gold ores contain cementitious aggregates, some of which are larger than 100 mm in size. If the mud mass does not break, it will be removed along with the waste rock during the screening process. It's easy to lose gold.

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.
