Why is chalcocite valuable?
Chalcocite is usually found in sedimentary rocks. The mining of chalcocite has taken place for centuries and is one of the most profitable ores due to its high copper content, which is nearly 80% by weight.
What is mineral chalcocite?
Chalcocite (/ˈkælkəˌsaɪt/), copper(I) sulfide (Cu2S), is an important copper ore mineral. It is opaque and dark gray to black, with a metallic luster. It has a hardness of 2.5–3 on the Mohs scale. It is a sulfide with a monoclinic crystal system. Chalcocite.
Where is chalcocite mined in Australia?

What is chalcopyrite used for?
Uses of Chalcopyrite The only important use of chalcopyrite is as an ore of copper, but this single use should not be understated. Chalcopyrite has been the primary ore of copper since smelting began over five thousand years ago. Some chalcopyrite ores contain significant amounts of zinc substituting for iron.
Which metal can be extracted from chalcocite?
copper
Today, copper is primarily obtained from the ores cuprite (CuO2), tenorite (CuO), malachite (CuO3·Cu(OH)2), chalcocite (Cu2S), covellite (CuS) and bornite (Cu6FeS4).
