  • Copper Sulfide

    All copper sulfides require the presence of Fe 3+ and O 2 as oxidizing agents for leaching to occur The copper sulfide is oxidized by Fe 3+The resulting Fe 2+ is reoxidized to Fe 3+ by O 2The Fe(II)/Fe(III) redox couple acts in a catalytic manner in these reactions (shown for elevated-temperature reaction conditions where the sulfur-containing product is sulfate, rather than the elemental ....

  • Sulfide Ores

    112 Extraction of Nickel and Cobalt from Sulphide Or Sulphide ores were mostly created by (i) the intrusion of molten magma from the mantle into the crust of the earth and (ii) the formation of localized metal-rich sulphide ore bodies by sequential solidification and/or ,...

  • Copper Sulfide Ore

    The concentration of these minerals in an ore body is low Typical copper ores contain from 05% Cu (open pit mines) to 1 or 2% Cu (underground mines) Cu-Fe-S minerals are not easily dissolved by aqueous solutions, so the vast majority of copper extraction from these minerals is pyro-metallurgy (Excerpt from Extractive Metallurgy of Copper)...

  • Nickel processing

    Nickel processing - Nickel processing - Extraction and refining: The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel ....

  • Nickel: smelting, producing

    In hydrometallurgical processes, nickel sulfide ores undergo flotation (differential flotation if Ni/Fe ratio is too low) and then smelted After producing the nickel matte, further processing is done via the Sherritt-Gordon process First, copper is removed by adding hydrogen sulfide, leaving a concentrate of only cobalt and nickel Then ....
