Refractory Sulfide Ores – Case Studies Sciencedirect

Nickel sulfide ores occur as disseminated or massive ore bodies All the nickel in nickel sulfide ores occurs in the mineral pentlandite hosted by silicate rock minerals referred to as gangue rockMetal sulfide minerals Bed controlled ore predominates subsequent regional metamorphism of stratabound deposits disseminated sulfide mineral bearing deposits and to project the extent of known deposits (Lindeman 1984) Because ore contains no base metals and extraction of sulfide minerals during ore processing is extremely efficient
