    Sodium hydrosulfide (NaHS) is a chemical reagent with numerous applications within predominately industries as below:

    Kraft Paper Milling
    In Kraft, pulping sulfidity is controlled through the use of reduction furnaces which reduce sodium sulfate plus caustic soda to sodium sulfide. Planned or unplanned, outages result in reduced concentrations of sulfidity. NaHS is typically introduced during these outages which may to return sulfidity levels to pre outage levels.

    Mining Flotation Agent
    In mining industry, NaHS is 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, it’s used to collector addition for the activation of Cu, Pb, and Zn minerals.

    Leather Depilatory
    NaHS solutions are applied in a process called blueing to remove hair from cow, calf, sheep or any other animal hide.

    Water Treatment
    NaHS is an effective tool in waste treatment programs requiring stabilization and reduction of heavy and toxic metals through precipitation.

    Besides, NaHS could also be used in the manufacture of colors and dyes, agrochemical chemicals as pesticides and fertilizers or other chemicals.
