Beneficiation of nickeliferous laterite by reduction ...

01/05/2012  Ni beneficiation of laterite ore by using direct reduction process is proposed. Sodium sulfate is capable of intensifying the reduction roasting of laterite. Average particle size of ferronickel grows up to 50 μm when reduced with Na 2 SO 4. Selective enrichment of Ni can be realized by suppressing the metallization of Fe. New-born troilite (FeS) facilitates the aggregation of ferronickel ...

Sodium sulfide - Wikipedia

Sodium sulfide can be used as nucleophile in Sandmeyer type reactions. Sodium sulfide reduces 1,3-dinitrobenzene derivatives to the 3-nitroanilines . [9] Aqueous solution of sodium sulfide can be refluxed with nitro carrying azo dyes dissolved in dioxane and ethanol to selectively reduce the nitro groups to amine ; while other reducible groups, e.g. azo group , remain intact.
