One of the most important ores of the copper mineral is chalcocite, and compared to other ores it has the most benefits. Chalcocite has a content of high copper, and copper can be easily separated from sulfur. Chalcocite is very scarce, and it is formed from the mineral's alteration of primary copper attacked by .
Always use a fresh surface to perform the hardness test. Sometimes the habit of the mineral will make a difference. For example aggregates of minerals may break .

Bioleaching involves the use of microorganisms to catalyze the oxidation of iron sulfides to create ferric sulfate and sulfuric acid. Ferric sulfate, which is a powerful oxidizing agent, then oxidizes the copper sulfide minerals and the copper contained is then leached by the sulfuric acid formed.
Bornite has a brown to copperred color on fresh surfaces that tarnishes to various iridescent shades of blue to purple in places. Its striking iridescence gives it the nickname peacock copper or peacock ore. Mineralogy. Bornite is an important copper ore mineral and occurs widely in porphyry copper deposits along with the more common chalcopyrite.
Chalcocite is an important copper mineral ore. It has been mined for centuries and is one of the most profitable copper ores. The reasons for this is its high copper content (67% atomic ratio and nearly 80% by weight) and the ease at which copper can be separated from sulfur. It is not however the primary ore of copper due to its scarcity.
COPPER This page looks at the extraction of copper from its ores, its purification by electrolysis, and some of its uses.
