According to the oxidation ratio 30%, mixed sulfide–oxide lead and zinc ore was composed of sulfide ore and oxide ore on the basis of the molar ratio of zinc sulfide to zinc oxide 3:1 by ball mill. Both these two kinds of zinc ore were from Lanping town in Yunnan province of China.
Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...
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 froth flotation.
From previous flotation investigations of mixed copper oxide and sulphide minerals using xanthate and Mineral processing hydroxamate collectors it was hard to distinguish the impact of the alkyl hydroxamate collector on sul-
Mar 24, 2018· Mining and Extraction: Oxide Ores - processes for extracting copper. Most of the copper ores mined today are oxide or sulfide ores. Extraction of The process used to treat sulfide copper ores begins at the mine site, where the copper-bearing minerals are physically separated from the rest of the rock. The flow
The copper sulphides present in the blend were bornite and chalcopyrite, while the oxides were malachite and minor azurite.From previous flotation investigations of mixed copper oxide and sulphide ...
Current copper deposits contain significant amounts of secondary non-sulphide minerals and newly discovered deposits are increasingly complex. As a result, research into the improvement of sulphide-oxide copper ores processing through the use of mixed collector systems has surged.
The Kansanshi Mine (First Quantum Minerals Ltd) treats a mixed sulphide/oxide copper-gold vein deposit. Until June 2009, the sulphide and oxide minerals were respectively recovered by the well ...

to traditional sulphide collectors, flotation plants can now process blends of sulphide and oxide minerals to produce saleable concentrates. Generally copper oxide minerals do not respond well to tradi-tional sulphide copper collectors and require alternative flotation techniques to concentrate the copper oxides. The classical method

The total and acid soluble copper assays of the tail from Test D were 0.19% and 0.16% Cu, respectively. This shows that the residual copper found in the tail was mainly associated with copper oxide minerals. The total copper, sulphide copper and oxide copper recoveries of 95.5%, 98.2% and 89.4%, respectively.
From previous flotation investigations of mixed copper oxide and sulphide minerals using xanthate and hydroxamate collectors it was hard to distinguish the impact of the alkyl hydroxamate collector on sulphide recovery as the sulphide and oxide minerals occurred naturally together.

These copper oxide ores are usually leached using sulfuric acid to liberate the copper minerals into a solution of sulfuric acid laden with copper sulfate solution.
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 ...
The process used to treat sulfide copper ores begins at the mine site, where the copper-bearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining.
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.
The recovery of oxide copper minerals from a complex . The ore deposit contains both primary and secondary copper minerals and is therefore classed into three distinct types, viz. sulphide, oxide and mixed.
