The oxidation of metal sulfides in soil involves both chemical and microbial processes and, as a result, is a more complex process than is the oxidation of S 0 Chalcocite (Cu 2 S), chalcopyrite (CuFeS 2), galena (PbS), pyrite (FeS 2), and nickel sulfide (NiS) are just a few examples of metal sulfides that are subject to microbial transformations.

Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago.
Covellite or Covelline is a rare copper sulfide mineral with chemical formula (CuS). The mineral was named after the Italian mineralogist N. Covelli in 1832. The color ranges between indigo-blue, brass-yellow, and deep red with lead-gray streak.

Although native copper was the dominant ore mineral, chalcocite (copper sulfide) was sometimes present, and, especially in the Mohawk mine, copper arsenide minerals such as mohawkite and domeykite. Gangue minerals included calcite, quartz, epidote, chlorite, and various zeolites .
The sulfide minerals represent higher temperatures and a slightly deeper setting than the sulfate minerals, which reflect the oxygen-rich environment near the Earth's surface. Sulfides occur as primary accessory minerals in many different igneous rocks and in deep hydrothermal deposits that are ...

The 10 biggest copper mines in the world. ... Copper concentrate is produced from sulphide ore of the mine through floatation. The mine also produces copper cathodes from oxide and sulphide leach ore. Sulphide ore comprises more than 82% of the mine's copper reserves.
Copper sulfides are crushed, ground, floated and the resultant concentrates are transported to smelters for refining into anodes. Today most copper oxides are liberated by solvent extraction. Ore is exposed to acid in a heap leach to liberate the copper ions.
In the present research, copper ores (copper oxide ore and copper sulfide ore) were crushed by a jaw crusher and by HPGR and the products were evaluated for particle damage and copper grain exposure by X-ray computed tomography.
