Thionocarbamate Collector (Z-200 Type)

Thionocarbamate collectors, represented by the Z-200 family, are highly selective copper collectors that provide excellent discrimination between chalcopyrite and pyrite in alkaline and mildly acidic flotation circuits. They are particularly valued in porphyry copper operations where minimizing iron sulfide dilution in the concentrate is critical to smelter penalties. Thionocarbamates are effective at low dosages and may be used alone or blended with xanthates.

Zinc Sulfate (Sphalerite Depressant)

CAS: 7733-02-0

Zinc Sulfate is the primary depressant for sphalerite (zinc sulfide) in differential lead-zinc flotation circuits, allowing selective flotation of lead minerals while zinc remains in the pulp for later recovery. When used in combination with sodium cyanide or sodium sulfite at alkaline pH, it forms stable zinc-hydroxide surface complexes that effectively prevent xanthate adsorption on sphalerite. Zinc Sulfate is essential in the classical lead-zinc selective flotation flowsheet.
