Sodium Hydrosulphide (NaHS) flakes, liquid, solid.
Mining: Flotation agent
NaHS is also used as a substitute for sodium sulphide for the sulphidization of copper, oxides of copper, lead or zinc making them amenable to collector attack.
Commonly used prior to collector addition for the activation of Cu, Pb, and Zn minerals. The choice of whether to use Na2S or NaHS depends on the pH required in flotation, as Na2S is more alkaline and also, whichever works best (test to verify). Typically made up to 15-25 % solution strength.
-For the removal of hair from hides.
Cloth and paper manufacture
As a makeup chemical for sulfur used in the Kraft process.
Though less effective than sodium sulphide, Na2S, sodium hydrosulphide usage translates to better saving because it is cheaper.
Our NaSH Sodium Hydrosulfide is produced in the newest facility in China with over 50,000ton annual production.

Sodium Hydrosulphide is recommended to be kept only in closed, properly labeled containers. Do nor store in zinc, aluminum, or copper containers. Sodium Hydrosulphide is stored in cool, dry, ventilated area to prevent it from being deliquescent. Separated from acids, acidic materials, oxidizing agents.
Inhalation: Inhalation of the dust can cause sore throat, coughing and shortness of breath. Very high or very long exposures could lead to a build-up of fluid in the lungs (pulmonary edema) and, possibly, death.
Skin Contact: Can cause severe skin irritation and burns.
Eye Contact: Can cause redness, pain, blurred vision and burns which are slow healing. Blindness may result.
