Sodium sulphide ore dressing medicament dressing sense of understanding
Sodium sulphide is non-ferrous metal oxide ore of activator, when adding quantity is large enough and inhibitors of sulfide ore. Sodium sulphide of preparing carbon based on coal, wood combustion as a reducing gas such as reduction of sodium sulfate (Na2SO4). Reactive for: Na2SO4 + 2 c = write Na2S + 2 co2
Sodium sulphide in is used as the inhibitor of sulphide ore flotation operation, in the production of molybdenum in the practice of using sodium sulphide restrain pyrite, molybdenite, using kerosene as collector flotation by natural flotability s.h. molybdenum very not by the inhibition of sodium sulfide, sodium sulfide that pyrite is restrained, after a few select qualified molybdenum concentrate.
When adding sodium sulphide ore pulp, pulp alkaline, make the surface of sulfide minerals generated a hydrophilic layer of hydrogen and oxygen compound film and hydrophilic, makes sulfide minerals is restrained.
