Mixed Copper Oxide And Sulphide Minerals Processing

Treatment of Mixed Sulfide Oxide Ores of Copper

Many of our largest copper deposits contain both sulfide and oxidized copper minerals. The large porphyry mines, with a total copper content of from 1.3 to 2.0 per cent., send to their mills ore with an oxide content of from 0.2 to 0.4 per cent.

Copper processing - Ores | Britannica

Copper processing - Copper processing - Ores: Principal forms in which copper ores are found include native copper, porphyry copper, massive deposits, and mixed ores. Native copper is simply the metal found unadulterated in nature. Occasionally copper is still found in its native form, but more frequently it is mixed with other minerals, some of which may have value themselves.

PROCESS OPTIMISATION OF MIXED COPPER ORES THROUGH …

and copper oxides. Depending on the degree of oxidation and consumption of acid by gangue minerals, these mixed ores are either treated through standard sulphide flotation, sulphidisation or flotation followed by acid leaching. The performance of each of these process routes depends on the degree of oxidation as predicted by the proportion of acid soluble copper present in the ore.

Copper extraction - Wikipedia

Sulfide ores. Secondary sulfides – those formed by supergene secondary enrichment – are resistant to sulfuric leaching.These ores are a mixture of copper carbonate, sulfate, phosphate, and oxide minerals and secondary sulfide minerals, dominantly chalcocite but other minerals such as digenite can be important in some deposits.. Supergene ores rich in sulfides may be concentrated using ...

Flotation of mixed oxide sulphide copper-cobalt minerals ...

For mixed oxide-sulphide ores, up to 80% of the copper and 60% of the cobalt is recovered in the sulphide concentrate while for the oxide concentrate, only 60% of the copper and 40% of the cobalt are usually recovered (Crundwell et al., 2011). With mixed oxide-sulphide ores, it is accepted practice to concentrate sulphide and oxide minerals in separate flotation processes.

Flotation of mixed copper oxide and sulphide minerals with ...

For mixed oxide and sulphide ores, CPS is unsuitable for simultaneous flotation of copper oxide and sulphide minerals, as the sulphides are usually heavily depressed by the sulphide ions from NaHS additions necessary to sulphidise the oxide copper.

Mechanochemical Sulfidization of a Mixed Oxide-Sulphide ...

Nov 11, 2019 · Mechanochemical sulfidization of a mixed sulfide/oxide copper ore by co-grinding with sulfur and additives including Mg(NO 3) 2 and Fe(NO 3) 3 salts and iron, aluminum and magnesium powders was investigated for the first time. Also, the influence of sulfidization during the wet-milling process was examined on the separation efficiency and recovery of copper in detail.

Flotation of mixed copper oxide and sulphide minerals with ...

The ore mined is from a primary copper sulphide deposit with separate additional deposits of copper oxides. In conjunction with Ausmelt Chemicals, Minto is currently investigating options to recover copper oxide and sulphide minerals using flotation by blending their primary sulphide ore with oxide ores.
