Dec 01, 2018 · Copper Mineral Uses and Properties - Geology. The uses and properties of the mineral Copper. It is rarely found in large quantities, thus it is seldom the primary target of a mining operation. Most copper produced is Today most copper is produced from sulfide ores. Copper is an
Copper sulfide ores must be concentrated before they can be economically transported and smelted. The universal technique for this concentration is froth flotation of finely ground ore. Froth flotation entails attaching fine Cu-sulfide mineral particles to bubbles and floating them out of a water–ore mixture.

The effect of copper price variations on optimum cut-off grades (mining capacity is the limiting factor), concentration cut-off grade ( ), Heap leaching cut-off grade ( ) As a result, while the objective is to maximize the net present value, leaching and concen- tration optimum cut-off grades of the hypothetical mine should decrease as copper .
Copper ores The main copper sulphide minerals are chalcopyrite (CuFeS2) chalcocite (Cu2S), covellite (CuS), bornite (Cu5FeS4), tetrahedrite ((Cu,Fe)12Sb4S13) and enargite (Cu3AsS4). The largest source of copper is from porphyry ore deposits in which one or a combination of the aforementioned minerals occurs.
4) Oxygen in the air reacts with Fe to form FeO, and leaves Cu in the form of CuS. S02 is a by product gas] 5) Silicon dioxide (sand) reacts with limestone and the FeO to form slag, FeSiO3 and CaSIO3 6)Excess sulfur in the ore reduces copper sulfide, CuS, to copper sulfide, CU2S, which metals and flows out the bottom of the furnace.
Secondary copper sulphide minerals such as chalcocite (Cu2S) or covellite (CuS), although not as abundant as chalcopyrite, represent a non-negligible source of copper. The enrichment zone of porphyry copper deposits (e.g. Morenci), or the sulphidic zones of Central African copper deposits, are examples of secondary copper minerals deposits .
Groups of 30-32 rats were given single im injections containing 20 mg of cupric oxide (16 mg copper), cupric sulfide (13.3 mg copper), and cuprous sulfide (16 mg copper) into the left and the right thigh of each rat. All animals were observed for up to 20 months, .
Five different copper sulfide samples were leached in the experimental equipment. Ore size distributions, weights, copper analyses, and mineral contents are shown in table 1. The first sample was a monzonite ore containing chalcocite (Cu2S) as the most abundant copper mineral with minor amounts of chalcopyrite (CuFeS2).
