Xanthate Application in Pyrite Froth Flotation

In flotation of pyrite with xanthate, butyl xanthate is usually used. Generally, after the activator (copper sulfate) is added to the pulp, the mixed emulsifier of xanthate, pine oil and water can be added at one time, which is better than the multiple addition of the flotation reagent, and the dosage of the flotation reagent will be saved. Pyrite can use xanthate as the collector in acidic, neutral and weak alkali slurries. The acid-treated pyrite has good floatability (the optimum pH for the use of xanthate is 4.5). For the flotation of pyrite, the ability of xanthate to collect is better than that of dithiophosphate.
