Oct 01, 2009  The oxidation rate of arsenic minerals and non-arsenic minerals has been compared in a series of papers to explain the selective flotation of arsenic minerals from other sulfide minerals. According to Iwasaki et al. (1988), nickel arsenide (Ni 11 As 8) is much more easily oxidized than pyrrhotite, pentlandite, chalcopyrite and cubanite.

Feb 19, 2010  1.. IntroductionThe principal nickel mineral in most nickel sulphide ores is pentlandite ((Fe,Ni) 9 S 8), which is recovered primarily by froth flotation.Pentlandite is nearly always associated with pyrrhotite, Fe 1 − x S, and is often associated with chalcopyrite, CuFeS 2, and other iron and nickel sulphides and arsenides.Arsenic present can occur in a range of minerals including ...
