| 内容記述 | In oder to research a rule of sulphur, the reduced pellets in which include several sulphur percentage are analyzed with x-ray diffractometer. The reduced pellets are also extracted with bromin -methanol solution for research the reducibility.Ni and Co extractions with sulphuric acid to the reduced pellets in which include 7.5 % sulphur are improved 1 30/0 in Ni and 70/0 in Co as compared with to no addition of sulphur.In case of no addition of sulphur, the reduced nickel elements present as Ni-Fe alloys such as tetrataenite and josephinite . Forsterites are almost recrystallized as forsterite ferroan . On the other hand, enstatites do not contain iron element almost. With increase of addition of sulphur , the peak intensities of tetrataenite and josephinite decrease rapidly and peak intensities of metallic iron increase remarkablely.Peaks of NiS, CoS and FeS appear at 1.0%, 2.5%, and 1.0% respectively. These NiS, CoS and FeS are dissolved easily with heated sulphuric acid.Therefore, it is understood that an additive sulphur of more than 5% promotes recrystallization of forsterite ferroan and reducibility of goethite.As a result, substitution between Ni(Co) and Fe is promoted and the formation of NiS and CoS are also increased . Addition of sulphur depresses the rising rate of PH during oxidation period with 03 and decreases the extraction of Mg, and oxidation time becomes longer. As a result, Fe^<2+> and Mn^<2+> are oxidized, sedimentated and removed effectively. | |||||
