Cuprous chloride is a whitish to grayish solid that occurs as the mineral nantokite. It is usually prepared by reduction of copper(II) chloride with metallic copper. The pure compound is stable in dry air. Moist air converts it to a greenish oxygenated compound, and upon exposure to light ...
These methodologies have been applied to ores from mines as they deepen where arsenic levels in concentrate are becoming prohibitive. In this paper copper–arsenic mineral removal from copper concentrates is reviewed.doi:10.1016/j.mineng.2012.03.032...
Copper slag as a mineral admixture substituted in fine aggregate at the levels of 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, and 100%. It was observed that the increase of fly ash and copper slag shows the improvement in the fresh properties. 20% fly ash used as optimum ...
OccurrenceCopper is the 26th most abundant element on Earth, but it is rare to find pure metallicdeposits. It is found in many different types of mineral ores, many of which are close to thesurface and easy to extract. It is found in two types of ores: (1) sulfide ores, such as cov...

Copper (CU) is an essential trace mineral, naturally available in some foods and as dietary supplements. CU is a cofactor for several enzymes, known as cuproenzymes, which are involved in connective tissue synthesis, energy production, iron metabolism, neuropeptide activation and neurotransmitter synth...
A copper concentrate obtained by flotation of a high grade copper ore containing chalcopyrite as a main mineral constituent is leached at a temperature of 100掳 C. or higher, and under a pressure greater than atmospheric pressure yielding a copper leachate containing ferric ions of at least 5 g...
