  3. 2. Leaching of Pyrrhotite from Nickel Concentrate

    University essay from Luleå tekniska universitet/Industriell miljö- och processteknik

    Author : Filip Abrahamsson; [2017]
    Keywords : Leaching; Pyrrhotite; Nickel Concentrate; Pentlandite; H2SO4; sulfuric acid; non-oxidative; acid leaching; Lakning; Magnetkis; Nickelkoncentrat; Pentlandit; H2SO4; svavelsyra; icke-oxidativ; syralakning;

    Abstract : Non-oxidative acid leaching of pyrrhotite from Kevitsa’s Ni-concentrate and methods to recover by-products, have been investigated. Selective dissolution of pyrrhotite (Fe1-xS, 0<x<0.25) can enrich the content of the valuable metals, such as Ni and Co, in the final concentrate and will reduce the amount of Fe and S sent to the smelters.
