A Review on Novel Techniques for Chalcopyrite Ore

2012-1-1  2.1.1. Factors Affecting the Mining of Chalcopyrite Factors which may contribute to the decision to mine or not to mine chalcopyrite mineral resources include the following: (a) The availability of the rock or ore is obviously necessary: When mining begins, the richest sources of ore are mined first and lower grade ore is mined later.

Bacterial Leaching of Chalcopyrite Ore

2021-3-24  Bacterial leaching utilises bacteria, ubiquitous to sulphide mining environments to oxidise sulphide ores. The sulphide mineral chalcopyrite is the most common copper mineral in the world, comprising the bulk of the known copper reserves. Chalcopyrite is resistant to bacterial leaching and despite research over the last 20-30 years, has not yet been economically bioleached.

Chalcopyrite: Mineral information, data and localities.

Chalcopyrite Group. Chalcopyrite-Eskebornite Series. A major ore of copper. Common in sulfide veins and disseminated in igneous rocks. Weathering may lead to the formation of malachite, azurite, brochantite, langite and numerous other secondary copper minerals. A Zn-rich variety is known from Atlantis II Deep (see zincian chalcopyrite).Also, the Mid-Atlantic-ridge isocubanite may transform to

When the leaching volume reached 10 m 3 /t ore, the CuT recovery of the JX Iodine Process for sample A increased linearly to 69.7% (56.0% higher than blank), while sample B increased to 52.7% (33.2% higher than blank) with a slight slowdown. In general, the leaching kinetics of primary-sulfide ore which is represented by chalcopyrite is slow.
