Ore flotation chemical - sodium Hydrosulfide

1.Usage: Cooper mining reagent,tanning, dye, chemical material, etc. 2.Sodium Hydrosulphide is yellow flakes or solid

Sodium Hydrosulphide is a unique alkaline product, playing a vital role in many industrial processes.

  

MANUFACTURING PROCESS:NaHS is primarily produced by scrubbing a H2S stream with NaOH, as shown in the following reaction:

Hydrogen Sulfide  +  Sodium Hydroxide  =  Sodium Hydrosulfide +  Water 

       H2S                       NaOH                             NaHS                H2O

Specification:

Sodium Hydrosulfide Applications:

NaHS is a key component in many industrial processes involving sulfur requirements.

 

SPECIALTY CHEMICALS

NaHS is used in various industries for applications including, but not limited to agricultural, dyes, and other chemical processing.

  

ENVIRONMENTAL APPLICATIONS

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

 

MINING

NaHS is an effective means of sulfidizing oxide ores and is used most commonly to separate Copper (Cu) from Molybdenum (Mo).NaHS does this by depressing the Cu from the Cu-Mo concentrate, allowing for conventional floatation metal separation.

PULP AND PAPER

NaHS is used in the Kraft pulping process to prepare synthetic cooking liquor (white liquor) during pulp mill outages and as amake-up chemical to replace lost sulfur values. It may also be used as a scrubbing media forresidual chlorine dioxide generated and consumed in mill bleach plants.

 

TANNING

NaHS is used for removing hair from hides at the beginning of the tannery process.

Packing: 25kgs plastic woven bags,or 900kgs jumbo bags.
