Syngenetic sulphide minerals in a copperrich bog ...Heavy mineral separates of peat from a mineralotrophic bog contain sulphide minerals with distinctive textures. Pyrite framboids, consisting of spherical aggregates of subhedral pyrite crystals, are surrounded by a thin rim of chalcopyrite or a layer of massive marcasite. Clusters of framboids are cemented by covellite which also occurs as small idiomorphic grains, with rectangular or ...
Leaching of copper sulphide mineralsCopper(I) sulphide was examined as a model substrate for investigating the mechanisms and kinetics of chalcopyrite bioleaching. Surface evaluation techniques allowed the rate of copper extraction to be directly related to the surface species and EPS composition. The findings demonstrated that copper(I) sulphide has a higher reactivity and unchanging EPS.
Copper | Earth Sciences Museum | University of WaterlooCopper generally starts as chalcopyrite, a sulphide, which is then oxidized and enriched by interaction with the atmosphere, naturally acidic rainwater and nearby rocks and minerals. The top of an enriched copper deposit is a spongy mass of iron oxides left behind when iron sulphate and sulphuric acid are removed from sulphide minerals.
Unlocking Value in Copper Arsenic Sulphide Resources with ...specific to copper arsenic sulphides are briefly discussed below [12]. Pressure oxidation involves oxidation of sulphide minerals at elevated pressure and temperature in the presence of alytic chloride ions. In the case of arsenic bearing concentrates, a significant portion of the copper value can be found in minerals such as enargite (Cu 3AsS
