Flotation to Recover Copper Minerals from a Low-Grade Copper-Bearing Iron Ore

Abstract:

Large amount of sourrounding rocks in Jianshui China has been discarded for many years, and the “rock” is characterized by Cu-Fe polymetallic constituents and of low grade. According to the results of chemical and phase analysis as well as the mineralogy, a joint pocess of flotation and magnetic separation was proposed and used to process the ore. Flotation results show that the combined processing technology is efficient in utilizing the low grade rocks. A copper concentrate assaying 20.68% Cu at the recovery of 80.11% can be obtained, when the raw material assays 0.79% Cu.
