discovered that heat made copper more malle-able. Casting and smelting of copper began around 4000-3500 B.C. see figure 6-2. About 2500 B. C., copper was combined with tin to make bronzean alloy that allowed stronger weapons and tools. Brass, an alloy of copper and zinc, probably was not
One of the main challenges in the copper oxide processing industry is implementation of flotation method to reduce operating costs. Sulphidising flotation is the most common used technique in which a sulphidisation agent is used to sulphidise the surface of the oxide minerals. In this research, the mentioned technique was used sequentially for the concentration of silicate-carbonate ore ...

This paper presents the sulfidisation promotion effect of ammonium sulfate on the sulfidisation flotation of both malachite and copper oxide ores. Copper oxide ores are commonly difficult-to-float due to its molecular structure, and adding sodium sulfide as activator is necessary however, its dosage to the flotation pulp must be strictly controlled, as it is also a powerful depressant for ...
Jul 12, 2021 The Complete Collection of Copper Beneficiation Reagents. In the flotation process of the copper mine, the use of flotation reagents to change the surface properties of the mineral is a flexible and effective way to control the flotation behavior. It is also an important reason why flotation can be widely used in mineral processing.
Flotation conditions are basically the same as malachite. The only difference is that it has better floatability than Malachite when flotation with aliphatic and soap, and it needs a long time of action with reagents when flotation with sulfide. CuSiO3 2H2O---Silicon malachite. This kind of copper oxide

The bench-scale flotation outcomes showed that TMATT achieved the high-efficient flotation separation and enrichment of copper oxide minerals from the mixed sulfide-oxide copper ore.
flotation of oxide copper-cobalt ores, using sodium hydrosulphide as the sulphidising agent, has been practiced in Katanga, Democratic Republic of Congo. With sodium hydrosulphide, nearly 77 of the copper and 75 of the cobalt were recovered with a
The aim of this study was the recovery of copper from the oxide copper ore by froth flotation and agitating sulphuric acid H 2 SO 4 leaching. The ore with 4.21 copper grade used in this study was obtained from orum-Dangaz region of Turkey. Native copper, cuprite Cu 2 O, tenorite CuO, and malachite Cu 2
Copper oxide ore has a complex composition, and a low recovery rate is often achieved via the traditional sorting method. A new combined process of flotationhigh-gradient magnetic separationleaching is proposed here to recover copper minerals. The test results showed that the flotation process was successful when using sodium sulfide as a vulcanizing agent and butyl xanthate as a collector.
