Chalcocite is an important copper mineral ore. It has been mined for centuries and is one of the most profitable copper ores. The reasons for this is its high copper content 67 atomic ratio and nearly 80 by weight and the ease at which copper can be separated from sulfur.

Oct 05, 2016 The Sudbury area has produced large quantities of copper from its copper-nickel ores. Deep diamond drilling has indicated that these ore-bodies may change at depth into richer copper ores. In the Parry Sound District, bornite, chalcocite, and copper pyrites are found in disseminated zones in schistose diorite and garnetiferous gneiss ...
In ores with pyrite in gangue material and host rock, acid is generated in the waste rock and the tailings, and present in the pumped mine water. The copper contained in chalcocite and bornite, results in the production of a concentrate which is relatively high in copper. Consequently less energy is wasted on shipping barren material in the ...
The proportions of carbonate, shale and sandstone ore types vary from mine to mine and the ore horizon ranges from 1.2m to 20m in thickness, lying at depths of between 600m and 1,200m from surface. The overall average thickness in the mineable zones is 3.38m. Chalcocite, bornite and chalcopyrite are the most important minerals.
Bornite occurs as abundant irregularly shaped replacement remnants sea islands that are being replaced by chalcocite. This polished section has been freshly polished and therefore the bornite is still tan in color. Butte, Montana copper ores. Ore microscopy, reflected light, medium magnification.

Copper can be extracted from various types of ores, most of which belong to the sulfidic ores such as chalcopyrite, bornite, covellite, digenite and chalcocite. Chalcopyrite is the most common copper-bearing mineral and accounts for approxi-mately 70 of the copper deposits in the world.1 At present,
Oct 01, 2019 The copper minerals chalcopyrite, chalcocite, and bornite are uniformly distributed in all size ranges in the ore sample under study. Silver, gold and PGM platinum group minerals are closely associated with these copper sulphides, although only in trace amounts.
Chalcocite, sulfide mineral that is one of the most important ores of copper. Valuable occurrences include deposits of sulfide minerals at Ely, Nev., and Morenci, Ariz., where other components of the original rock have been dissolved away it is also found with bornite in the sulfide veins of Tsumeb, Namibia, and Butte, Mont.
Bornite, a copper-ore mineral, copper and iron sulfide Cu 5 FeS 4. Typical occurrences are found in Mount Lyell, Tasmania Chile Peru and Butte, Mont., U.S. Bornite, one of the common copper minerals, forms isometric crystals but is seldom found in these forms. It alters readily upon weathering to chalcocite and other copper
Nov 19, 2020 2.1.2. Mixed Copper Sulde Minerals Ore Sample for Mixture Mineral Flotation Tests A Chilean copper ore sample that contained chalcocite, bornite, and chalcopyrite was used in the mixture mineral otation tests. The mineral composition of the sample analyzed using a Mineral Liberation Analyser MLA 650, FEI, Tokyo, Japan is shown in ...
Copper Mining and Extraction Sulfide Ores Answers. 1. Place these products in the extraction process in ascending order of copper content. 2. Use a periodic table to find the atomic masses of the elements in cuprite and chalcocite. Then work out the percentage of copper in each mineral. Dont forget to double the copper mass as it is Cu2.
Although the degree of enrichment fractionation factor is different for a variety of copper sulfides chalcopyrite, chalcocite, bornite, and enargite, in each case, the reactions produce cupric copper Cu 2 in solution which always has greater than the starting mineral.
