3 Major Roles of Sodium Sulfide in Mineral Processing
Oct 29, 2021Sodium sulfide is a vulcanizing agent for non-ferrous metal oxide ore Non-ferrous metal oxide ore cannot be directly collected by xanthate. However, if sodium sulfide and non-ferrous metal oxide ore are added before the flotation of xanthate, a film of sulfide ore can be produced on the surface of the mineral, and the xanthate can be collected.

Because the new ore is a binary metal sulfide, you could take advantage of the hydrophilic nature of most metal sulfides to separate WS 2 by froth flotation. Then, because most metal sulfides cannot be reduced directly to the metal using carbon, you will probably need to convert WS 2 to an oxide for subsequent reduction.

Sulfide ore grades range from 0.15-8% Ni, with 93% of known deposits ranging from 0.2-2% Ni. All nickel ores have relatively low nickel content, the classification is as follows: high-grade nickel ore has Ni content greater than 1.8%, middle-grade nickel ore has Ni content between 1.3-1.7%, low-grade nickel ore has Ni content between 0.6-1.2%.
