Product Description

Directed from factory

Sodium Hydrosulphite

Physicals:
Sodium Hydrosulphide (thickness: 1mm-2mm), less impurity and higher content of NaHS, lower iron, . Sodium Hydrosulphide is needle system crystal, easily being deliquescent, soluble in water and alcohol, water solution with strong alkaline. Sodium Hydrosulphide react with acids and liberates hydrogen sulfide. Industrial grade of Sodium Hydrosulphide is generally in solution form with pale yellow color, slight rotten egg smell. Available form: Flake form and solid fused form.

Application
Mining industry
As the activator for the sulfidization of oxide minerals. Florrea NaSH has a much lower alkalinity than Na2S. When in contact with oxygen (air), it lowly oxidizes. If a solution of NaSH is heated, it is converted into Na2S and H2S. It is a good replacement
For NsS.
As the flotation depressant for Cu and Fe sulfide minerals in Cu/Mo separation
Leather industry (tanning) as de-hairing agent
Pulp and paper industry, metal extraction from aqueous solutions,
Textiles (sulphur dye) and chemical processing
