Deenah Osman, Jennifer S. Cavet, in Advances in Applied Microbiology, 2008. A The properties of copper. Copper is widely distributed in the environment; present mainly in minerals as sulphides, oxides, or carbonates, with the major ores being chalcopyrite (CuFeS 2), chalcocite (Cu 2 S), cuprite (Cu 2 O), and malachite (Cu 2 CO 3 (OH) 2).Copper was the first metal to be worked by human ...

Through industrial testing at the Huize lead-zinc mine, it was found that the floatability of sphalerite varied greatly with the iron impurity content. Three kinds of Huize sphalerites with iron contents of 2.30 wt.%, 3.20 wt.% and 4.66 wt.%, were used to study the influence of small amounts of iron impurity in the sphalerite on xanthate adsorption and flotation behavior.

The Flotation of Chalcocite, Bornite, Chalcopyrite, and Pyrite in an Electrochemical-flotation Cell. The flotation edge occurs at more reducing potentials as the copper-to-iron ratio of the minerals increases. Linear sweep voltammetry and ultraviolet spectrophotometry were used to study the reaction mechanisms between the minerals and ...

Heap Leaching Oxide and Sulfide Copper Ores

Other sulphide minerals also typically associated in PGM ores are chalcopyrite, chalcocite, pyrrhotite and pyrite. The actual PGMs are generally associated with all these minerals. These ores often have very high talc content which significantly impacts flotation.

Jul 09, 2019· 1 Types of copper sulfide ore (1) Single copper mineral Its ore characteristic is relatively simple, and the only useful component that can be recycled is copper. The gangue minerals are mainly quartz, carbonate and silicate. (2) Copper-sulfur ore Called copper-bearing pyrite. In addition to copper minerals, iron sulfide can be recovered, and the main mineral of sulfur is pyrite.

Copper Mining and Extraction Sulfide Ores

The flotation behaviors of chalcocite and molybdenite as a function of TGA dosage are indicated in Fig. 5. Recovery of chalcocite shows a substantially descending tendency with addition of TGA, while recovery of molybdenite is essentially constant with trivial decline. All this shows TGA is an effective inhibitor for chalcocite.

XA04N0873

Description. A process that allows selective flotation separation of low Cu/S ratio minerals (chalcopyrite and pyrite) from high Cu/S ratio minerals (bornite and chalcocite) from a mixed copper mineral concentrate under controlled oxidative-reductive potential conditions has been developed.

Chalcocite

Oxidative leaching of metals by Thiobacillus ferrooxidans has proven useful in mineral processing. Here, we report on a new use for T. ferrooxidans, in which bacterial adhesion is used to remove pyrite from mixtures of sulfide minerals during flotation. Under control conditions, the floatabilities of five sulfide minerals tested (pyrite, chalcocite, molybdenite, millerite, and galena) ranged ...
