Zinc - Wikipedia

Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States. Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity ...

Copper-Zinc ores - Danafloat - Home

Combinations of xanthate with either dithiophosphate and/or thionocarbamate are used in combination with xanthate in the sphalerite flotation but often the collector selection tends to be toward weaker collectors. A similar frother strategy is used, although as always, circuit and ore conditions impact specific reagent selection.
