The key to the gold flotation process is adjusting the flotation conditions so that gold particles can combine with air bubbles and float, while other minerals do not. In practical application, optimizing and adjusting the process according to the specific situation is necessary to obtain the best gold recovery rate and quality. 1.

Gold Ore Mining. Placer gold mining mainly refers to mining from the land surface or river or underground. It mainly uses gravity separation because its density is much bigger than other minerals. Compared with placer gold, rock gold ore has higher gold content and mining value, but the beneficiation process of rock gold ore is much more complicated than that of placer gold ore.
