Action selectivity of consecutive use of collectors during flotation of copper-zinc ore
Journal Title: Metallurgical and Mining Industry - Year 2017, Vol 9, Issue 1
Abstract
Today selective flotation of copper-zinc-pyrite ores at deterioration of the technological properties of raw material is one of the most important problem. The solution of this problem involves the use of more selective collectors combined with the main reagent-collector – xanthate. The article presents the study results of competing adsorption of butyl xanthate and dithiophosphate BTF-1541 on non-activated sphalerite. Discovered dependences of flotation of chalcopyrite, sphalerite and pyrite with xanthate and dithiophosphate combinations depending on the pH of the pulp, which had allowed establishing the optimal proportions of collectors for each cycle of collectively selective flotation were described. Extraction of zinc using xanthate during ore processing according to scheme adopted on the factory is not more than 53%. As a result of changes in reagent regime, reduction of zinc losses in the copper cycle by 3.64% and a more complete extraction of metals in the same name concentrates were obtained. Recovery of copper in copper concentrate was increased by 2.84%, zinc extraction in the zinc concentrate – by 13.25%.
