1. It is used to synthesize organic intermediates and auxiliary agents for the preparation of sulfur dyes.
2. In the tanning industry, it is used for dehairing and tanning of leather, and also for waste water treatment.
3. In the chemical fertilizer industry, it is used to remove the monomer sulfur in the activated carbon desulfurizer.
4. It is the raw material for the manufacture of semi-finished products of ammonium sulfide and pesticide ethyl mercaptan.
5. The mining industry is widely used in copper ore beneficiation.
6. Used in sulfurous acid dyeing in man-made fiber production.
