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 copper from the molybdenum 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 a make-up chemical to replace lost sulfur molecules. It may also be used as a scrubbing medium for residual chlorine dioxide generated and consumed in mill bleach plants.
Speciality Chemicals
NaHS is used in various industries for applications including but not limited to agricultural, dyes, and other chemical processing.
Tanning
NaHS is used for removing hair from hides at the beginning of the tannery process.
