Copper Flotation - Mineral Processing Metallurgy

2016-5-16  The flotation of native copper ores is nearly always preceded by gravity concentration in jigs and tables not only because the combined process is more economical as regards costs, but also because the copper often occurs as large grains which flatten out during grinding and cannot be broken to a size small enough for flotation.

Flotation of copper sulphide from copper smelter slag ...

2015-10-10  Adkins and Pearse (1992), in a study of the flotation of a mixed copper sulphide/oxide ore, showed that a mixture of isopropyl xanthate and dicresyl DTP resulted in enhanced rates and recoveries of copper. Synergistic effects in flotation were also reported by Finch and Smith (1972). They observed that mixtures of surfactants can cause a greater lowering of surface tension than that predicted for

Recovery of Copper from the Slag of Khatoonabad Flash ...

2013-6-5  At the grinding rate of 85 % −74 μm, a significant change in the recovery of copper was observed, and at the flotation time of 14 min, a 90.6 % recovery of copper was obtained. By increasing the grinding to the extent of 93 % −74 μm, no significant change occurred in the copper recovery, and the grade and recovery of copper were recorded to have minimum values of 15.3 and 90.4 %, respectively.

Recovery of Copper from Ammoniacal Leachates by Ion Flotation

2021-4-27  From the optimization of the ion flotation parameters, it can be concluded that copper was best separated over zinc under the following conditions: [SDS] total = 5.85 mmol L −1, t total = 5 h and three ion flotation steps. To evaluate the efficiency of the optimized technique on realistic conditions, the recovery of copper

2019-1-1  The micro-flotation results show that combined use of NaBX+DDA yields better effect than using NaBX at pH 7-11 only, and the optimal molar ratio of NaBX to DDA is 2: 1. The actual ores flotation shows that when the dosage of NaBX+DDA is (100+54) g/t, the copper concentrate grade and recovery are 15.93% and 76.73%, respectively.
