Apr 23, 2011· Both ore types can be economically mined, however, the most common source of copper ore is the sulfide ore mineral chalcopyrite, which accounts for about 50 percent of copper production.
Kamoto Underground Mine. The Kamoto underground mine is Katanga's primary sulfide ore source. It entered operation in 1969 under the DRC's stateowned mining company Gécamines. During the 1980s it produced an average of three million tonnes of ore per year and, prior to its restart under Katanga's ownership, the mine had produced a total ..
· Traditionally, nickel has been processed from sulfide ores in an approach similar to copper processing, in which the ore is upgraded to concentrates and then smelted. As sulfide ore resources dwindle, however, processing of lateritic nickel ores is becoming of greater necessity, with many recognizing nickel laterite ores as the future of the ...
Recovery of Gold in Pyritic Sulfide Ores The now extinct Us Bureau of Mines conducted numerous studies of gold in pyrite, and sulfide ores over the years, until their untimely demise in the 1990's. Much of the referenced studies and case applications discussed in this brief article came from USMB reports, which even after they ceased to exist ...

Immiscible sulfide drops can become segregated and form immiscible magma layers in a magma chamber in the same way that cumulus layers form; then, when layers of sulfide magma cool and crystallize, the result is a deposit of ore minerals of copper, nickel, and platinumgroup metals in a gangue of an iron sulfide mineral.
Metallurgical processing of sulfide ores presents problems similar to those found in the treatment of refractory gold ores that contain sulfide minerals and carbonaceous matter. These problems are being addressed at the production level by methods such as pressure .

Except occurring as silver minerals, silver in gold ores is often present in electrum, and occasionally in kustelite. Silverrich electrum and kustelite tarnish quickly in air, and form a silver sulfide layer of 12 µm in thickness in the presence of sulfide ions, which can limit the access of cyanide solution.
Jan 14, 2017· Hari om, you are asking a question as to : "Why is roasting carried out in sulfide ores and not on carbonate?". Browse the following site for details on your question : why is roasting carried out on sulphide ores and not on carbonate ores? Hari om.
Copper sulfide ore has good inherent floatability, so flotation process is a mature method used for copper sulfide ore separation. In recent years, with the continuous development of copper sulphide flotation technology, many scholars also proposed a series of new principles of mineral processing, such as "collect early, loss early" and "more crushing and less grinding".
