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.
The gold mining operation stage represents the productive life of a gold mine, during which ore is extracted and processed into gold. Processing gold involves transforming rock and ore into a metallic alloy of substantial purity – known as doré – typically containing between 60-90% gold. During its life, a number of factors – such as the ...

The mineralization of this period is represented by pyritization developed along mylonitic foliation. The middle period of gold mineralization formed the main economic gold ores in the Jiaodong Peninsula. The late auriferous silver mineralization took place in late Yanshanian (90–80 Ma) due to the formation of volcanic–intrusive rocks.
The Kalgoorlie Gold Field lies approximately in the centre of the well-endowed, Neoarchaean, Kalgoorlie granite-greenstone Terrane in the eastern Goldfields Province of the Yilgarn Craton in Western Australia (Fig. 1).The Gold Field is centered in and around the Golden Mile dolerite and is characterized by two dominant ore types: …
The principal gold minerals that affect the processing of gold ores are native gold, electrum, Au-Ag tellurides, aurostibite, maldonite, and auricupride.
