Chalcocite Facts - Softschools.com

One of the most important ores of the copper mineral is chalcocite, and compared to other ores it has the most benefits. Chalcocite has a content of high copper, and copper can be easily separated from sulfur. Chalcocite is very scarce, and it is formed from the mineral's alteration of primary copper attacked by oxygen. The color of chalcocite may be black or blackish-grey, with a grayish ...

Chalcocite - Assignment Point

Chalcocite. Definition. Chalcocite (Cu 2 S) is a lead-grey or black mineral, found as a copper ore or in veins. It is a source of copper. It is most commonly found as a supergene mineral in the enriched zones of sulfide deposits. It is also occurs in hydrothermal veins. It has a hardness of 2½ – 3 on the Mohs scale.

Chalcocite - Celestial Earth Minerals

Chalcocite: The mineral Chalcocite information and pictures

Chalcocite is an important copper ore. It has a high copper content and the process of extracting the copper from the sulfur in Chalcocite is relatively easily. Chalcocite is also an important collector's mineral, and good crystals command very high prices.

Chalcocite - an overview | ScienceDirect Topics

Copper is most commonly present in the earth's crust as copper–iron–sulfide and copper sulfide minerals, for example, chalcopyrite (CuFeS 2), bornite (Cu 5 FeS 4), and chalcocite (Cu 2 S). The concentrations of these minerals in an ore body are low. Typical copper ores contain from 0.5% Cu (open-pit mines) to 1−2% Cu (underground mines).

Solvometallurgical process for extraction of copper from ...

Extraction of copper from sufidic ores, either by pyrometallurgy or hydrometallurgy, has various limitations. In this study, a solvometallurgical process for the extraction of copper from sulfidic ore minerals (chalcopyrite, bornite, chalcocite and digenite) was developed by using an organic lixiviant (FeCl 3 as oxidizing agent and ethylene glycol (EG) as organic solvent).

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,

Chalcocite - an overview | ScienceDirect Topics

Copper can be found in more than 200 minerals, but only about 10% of this occurs in the form of sulphide minerals (e.g., chalcopyrite, bornite and chalcocite) or oxidized minerals (e.g., cuprite), which are of significance as copper ores (Lossin, 2001).Depending mainly on the ore type, as well as the geographical, economic and environmental considerations, copper can be extracted through:
