  • Contrasting regimes of Cu, Zn and Pb transport in ore

    The predicted Cu, Pb, and Zn concentrations compare well with natural geofluids, and therefore the model fluids can be applied to investigate hydrothermal ore-forming process. (2) In both low- and high-salinity fluids, Cu, Pb and Zn are transported as hydrosulfide complexes at high temperature, but as chloride complexes at low temperature.

    The nature of Canatuan sulphide deposit allowed the staged processing of the ore from high Cu-low Zn ores to low Cu-high Zn ores. Due to this mineralogical stratification, emphasis on the high Cu-low Zn ores was set for the initial 1-2 years of operation. This provided some time to gather enough plant data

    Ore is natural rock or sediment that contains desirable minerals, typically metals, that can be extracted from it. Ore is extracted from the earth through mining and refined, often via smelting, to extract the valuable element or elements.. The grade of ore refers to the concentration of the desired material it contains. The value of the metal an ore contains must be weighed against the cost
