Main points of mineral processing of three types of gold ore
Companion gold in polymetallic mines often contains minerals such as arsenic and carbon, which have a certain impact on the flotation of gold ore. The mineral processing methods include cyanide leaching, flotation, gravity separation, and so on. This article will provide answers to three questions: how to process gold sulfide ore, how to …Web
