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 …A $1.2bn expansion project was approved for the mine in December 2017 to double sulphide ore processing capacity from 25Mt to 50Mt. The expansion project is anticipated to commence production in the second half of 2021 and will increase copper production from sulphide ore to 170,000t between 2022 and 2027 and to 130,000t thereafter.

THE MINERAL CHALCOCITE Chemistry: Cu 2 S, Copper Sulfide Class: Sulfides Uses: As a minor ore of copper and as mineral specimens. Specimens Chalcocite is an important copper mineral ore. It has been mined for centuries and is one of the most profitable copper ores.The copper sulphides are enriched from 34% copper in chalcopyrite to 66% in covellite, one of the minerals formed in this enriched zone. By this process, copper is taken from the upper parts of an ore body and deposited at the water table. Below the enriched zone, the sulphides may not be concentrated enough to carry the cost of deep mining.
