mineral copper sulphide
CHALCOCITE (Copper Sulfide)
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.

List Sulphide Minerals
The sulphide minerals are compounds of the metals with sulphur. Nearly all these minerals have a metallic luster, i.e., the peculiar shining appearance of metals, such as gold, silver, copper, lead, tin, iron, etc. They are all heavy minerals and nearly all are of economic importance. Iron Pyrites or Pyrite. FeS2.

Copper Sulfide
Copper sulfide minerals require the use of acid and an oxidizing agent to break the mineral lattice and release Cu2+ into solution ( Sherrit, Pavlides, & Weekes, 2005 ). Elemental copper found in nature can be leached by either oxygen or ferric ion: (15.6a) Metallic copper: Cu + 0.5 O 2 + H 2 SO 4 → Cu 2 + + SO 4 2 − + H 2 O.

What is the sulphide ore of copper?
Copper ores. The main copper sulphide minerals are chalcopyrite (CuFeS2) chalcocite (Cu2S), covellite (CuS), bornite (Cu5FeS4), tetrahedrite ((Cu,Fe)12Sb4S13) and enargite (Cu3AsS4). The largest source of copper is from porphyry ore deposits in which one or a combination of the aforementioned minerals occurs.

Dissertations / Theses: 'Sulphide minerals' – Grafiati
This thesis pertains to the extraction of copper via heap bioleaching, focussing specifically on the bioleaching of the mineral sulphide, chalcopyrite (CuFeS2). Industrial heap bioleaching offers an attractive alternative to conventional extraction methods, such as smelting, for processing low grade ores.

Direct extraction of copper from copper sulfide minerals using deep
Sulfide in the mineral is oxidised to sulfate without the generation of SO 2 or H 2 S. The best selective recovery of copper (99 at%) from chalcopyrite was obtained with a mixed DES of 20 wt% choline chloride-oxalic acid and 80 wt% choline chloride-ethylene glycol.

MASSIVE SULPHIDE DEPOSITS
The main Ni- and Co-bearing mineral is pentlandite [(Fe,Ni)9S2] while the main copper mineral is chalcopyrite [CuFeS2]. The deposits also typically contain a lot of pyrrhotite, an iron sulphide that is of no commercial value but which is an important factor in exploration as it is magnetic and can be detected by magnetometer surveys (see below).
