  • Sulfide Mining Minnesota Center For Environmental

    sulfide-ore mining for copper and nickel, however, has never been attempted here. In the case of polymet, mcea has led the fight for accountability and true science-based decision-making. mcea lawyers and experts have time and again cast light on the flaws inherent in the polymet proposal, first in the environmental review and permitting excellent cobalt-nickel separation primary leach liquor by cyanex 272. however, manganese extraction from the leach liquor along with cobalt could not be avoided, thus increasing the cost of the process. for sulphide ores, there is another alternative; if the ore can be concentrated by flotation, matte smelting is used instead of leaching.

  • Flotation Of Nickel Copper Sulphide Ore Optimisation

    the nickel-copper sulphide ore used in this study was supplied by trojan nickel mine located in bindura, zimbabwe. from the x-ray diffraction analysis, the main phases present in the ore were pentlandite pyrrhotite and quartz fig.1. the ore which was supplied in lumpy form was subjected to crushing and grinding.the nickel content in such sulrde ores is generally low and varies from place to place in the same deposit. the low nickel content of the present-day nickel sulrde ores renders them unsuitable for either direct smelting or hydrometal-lurgical extraction, thus requiring benerciation. the usual method of nickel extraction from sulrde

    types of copper sulfide ore single copper mineral its ore characteristic is relatively simple, and the only useful component that can be recycled is copper. the gangue minerals are mainly quartz, carbonate and silicate. copper-sulfur ore called copper-bearing pyrite. In addition to copper minerals, iron sulfide can be recovered, and the main mineral of sulfur is pyrite.pentlandite is an important ore of nickel. however, it does not produce good crystals and is generally only found in massive form. It is commonly associated with other sulfides such as pyrite, chalcopyrite and pyrrhotite in basic igneous rock intrusions. these sulfide ore bodies are probably produced through magmatic segregation.
