Sodium Hydrosulfide

Sodium hydrosulfide is an inorganic compound, the chemical formula is NaHS, is a white crystalline powder, soluble in water and alcohol, used in the dye industry for the synthesis of organic intermediates and preparation of sulfide dyes, in the leather industry for raw skin hair removal and tanning leather, in the fertilizer industry for the removal of activated carbon desulfurizer monomer sulfur, in the mining industry is widely used in copper ore processing. It is used in the production of artificial fibers for sulfite dyeing.

The application of sodium hydrosulfide in mineral processing mainly includes its reduction in copper ore processing and its role in non-ferrous oxide ore vulcanization. ‌ ‌

In copper ore processing, sodium hydride sulfide is widely used in reduction processing. Due to the slow vulcanization reaction, the reverse oxidation reaction is difficult to control, and the sulfide film is easy to loose and fall off, resulting in the sulfurization flotation index is sometimes not ideal. In order to enhance the stability of sulfide film after curing reaction, it is often necessary to add excessive curing agent to maintain sufficient reducing atmosphere. Sodium hydrosulfide has strong reducibility, which can prevent the occurrence of reverse oxidation reaction, thus improving the index of vulcanization flotation.

In the vulcanization process of non-ferrous oxide ores, sodium hydrosulfide is used as a vulcanizing agent. When sodium sulfide or sodium hydroxide reacts with oxide ore, it can produce a sulfide film on the surface of the mineral, which makes xanthate can collect it, thus realizing the vulcanization of nonferrous metal oxide ore. After vulcanization, the surface color of the mineral will change, such as the surface of white lead ore from white to dark, and the surface of malachite from green to black, which indicates that the vulcanization reaction is successful.
