Bioleaching of copper ore flotation concentrates ScienceDirect
The results of the leaching of gold–copper concentrate are shown in Fig. 1. As can be seen the best results were obtained at 12% and 15% of solid. The surface area of gold-bearing flotation concentrate increased from 2.92 to 7.33 m 2 /g and 7.37 m 2 /g after 168 h (7 days) biooxidation. The effect of the ferrous iron concentration on the.The copper ore in Chilean copper porphyry deposits is often associated with molybdenum minerals. This copper–molybdenum (Cu–Mo) sulfide ore is generally mined from various locations in the mining site; thus, the mineral composition, oxidation degree, mineral particle size, and grade vary.

The Effect of Hydrodynamic Conditions on the Selective Flotation
Low grade sulfide ores are difficult to process due to their composite mineralogy and their fine grained dissemination with gangue minerals. Therefore, fine grinding of such ores becomes essential to liberate valuable minerals. In this research, selective flotation was carried out using two pitched blade turbine impellers with Conclusions. The outcome of this work has shown that desliming improves the flotation response of the Kansanshi mixed copper ore. At a rougher copper concentrate grade of 8%, metal recoveries obtained with desliming were in excess of 70% compared to 58% achieved with baseline tests without desliming.Effect of Desliming on Flotation Response of Kansanshi Mixed Copper Ore
