Volcanogenic massive sulfide ore deposit - Wikipedia
Volcanogenic massive sulfide ore deposits, also known as VMS ore deposits, are a type of metal sulfide ore deposit, mainly copper - zinc which are associated with and created by volcanic -associated hydrothermal events in submarine environments. [2] [3] [4] These deposits are also sometimes called volcanic-hosted massive sulfide (VHMS) deposits.

Acid leaching of a copper ore by sulphur-oxidizing microorganisms
The ore sample contained 0.64% Cu as determined by atomic absorption analysis following acid-digestion of a blended sample (Taylor and Reisman, 2000).Copper occurred as brochantite Cu 4 SO 4 (OH) 6 and as malachite Cu 2 CO 3 (OH) 2 as determined by X-ray diffraction (XRD). Although XRD detected no other copper minerals, a small amount of …

Heap Leaching Oxide and Sulfide Copper Ores
Accuracy. Heap leaching is a simple means of recovering copper from oxide and oxide-sulfide ores. Although this method requires relatively low capital investment, it suffers from low copper recoveries and relatively high acid consumption. The objectives of this study were (1) to determine what factors influence these shortcomings, and (2) to ...

sulphur and copper ore - fdep.ch
A typical copper ore contains between 0.5 and 2.0 copper. A high grade ore produces a high yield of metal. A low grade order produces a low yield of metal. Copper can be extracted from sulfide ores (usually higher grade ores) by direct smelting. The earliest evidence of copper smelting occurs in Serbian artefacts dating from around 5000 BC.

In the extraction of copper from its sulphide ore?
The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite (CuFeS2) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper.
