More InfoChalcocite 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.
More InfoMar 29 2016 · Chalcopyrite is a copper iron sulfide mineral and its chemical formula is CuFeS 2. This mineral is naturally presented in a variety of ores from huge masses to irregular veins and it is considered as the most important copper ore. Chalcopyrite oxidizes to several types of oxides hydroxides and sulfates when it is exposed to the air.
More Infoorganic acid was used as an alternative for mineral acid for extraction of copper from chalcopyrite.41 42 However these systems were in general water-rich processes. In this paper we describe a green solvometallurgical process for the extraction of copper from sulfidic ore minerals with the emphasis on chalcopyrite. The preferred organic
More InfoAlthough the processing costs are higher ultimately more copper can be extracted. Since each mine site is unique in its mineral composition concentration and quantities the most economical and profitable processing of ore must be determined by the mine planners.
More InfoHigh Ag values are due to submicroscopic inclusions of Ag-bearing minerals. Chalcopyrite. This is a common accessory ore mineral throughout the deposit. The grain size varies from 0.02 to 0.1 mm. It occurs in Ag-rich parts of the ore intergrown with Ag minerals and in the calc-silicate layers together with pyrrhotite sphalerite and galena.
More InfoBornite is an ore mineral of copper and is known for its iridescent tarnish. "Peacock Ore" which is sold to amateur mineral collectors and tourists is often labeled as a variety of Bornite. However most Peacock Ore in reality is Chalcopyrite treated with acid which produces a strongly-colored
