Enhanced Nonferrous and Noble Metal Recovery in Scheelite-Sulfide Ore Flotation with Aeroflot Reagents

摘要

The flotation properties of new dialkyldithiophosphates (BTF-163, BTF-175) are compared with the standard basic Aeroflot reagent IMA-I413 and butyl xanthate during flotation of scheelite-sulfide ore. The selectivity of the test Aeroflot reagents in separation of chalcopyrite, magnetic pyrite, pyrite and arsenopyrite is illustrated in the article together with the option of enhanced extraction of copper and noble metals with the reduced arsenic content of the copper concentrate. The best results are obtained with BTF-163 that is recommended to industrial testing.
