SODIUM HYDROSULFIDE

Sodium hydrosulfide, also known as sodium bisulfide, is an inorganic chemical compound with a strongly alkaline and reducing nature, widely used in mining, chemical, paper, tanning, and water treatment industries. It is generally marketed in aqueous solution (30–45%) or in solid form, and is characterized by its high reactivity, intense hydrogen sulfide (H₂S) odor, and corrosive nature.

Uses and Applications

Depressant in the flotation process
Sulfidizing agent for oxidized copper minerals in flotation. It is a depressant for copper and iron to separate molybdenum. It is similar to sodium sulfide, but with easier dosage control.
