Improvement of reagent flotation modes of sphalerite and pyrite from deposits of copper-zinc pyrite, polymetallic copper-zinc pyrite and polymetallic ores

Copper-zinc pyrite (Sulphide) and polymetallic ores of Russia are complex and difficult to process mineral raw materials. The main technology for the enrichment of this ores are flotation. Currently, the improvement of the flotation technology of this mineral raw materials is carried out in several way. It has been established by the practice of beneficiation of copper-zinc ores that obtaining high-quality zinc and pyrite concentrates is impossible without adding flotation modifiers of sphalerite and pyrite to various flotation operations. This reagent are copper (II) sulfates, zinc and iron (II) sulfates in an alkaline calcareous medium. Therefore, studies on the flotation of sphalerite and pyrite in an alkaline calcareous medium with the addition of one of these metal sulfates to the mineral flotation operation were performed. The effect of each copper (II) sulfates zinc, and iron (II) on the flotability of sphalerite and pyrite was studied during flotation of the mineral and xanthate and dithiophosphate at pH = 8, 10, and 12. The aim of this work was to study the effect of the flotation size class (- 0.074 + 0.044 mm) sphalerite and pyrite of one of the Russian deposits by sulfhydryl collectors in the presence of copper, zinc and iron sulfates in the liquid phase of flotation pulp

IMPROVEMENT OF REAGENT REGIMES OF FLOTATION OF SPHALERITE AND PYRITE FROM SILVER COPPER-ZINC AND POLYMETALLIC ORE DEPOSITS

Pyrite copper-zinc (sulfide) and polymetallic ores in Russia are complex and refracto-ry mineral raw materials. The main processing technology for such ores is flotation. Currently, the improvement of the flotation technology of such mineral raw materials is carried out in several directions. It has been established by the practice of enrichment of copper-zinc ores that obtaining high-quality zinc and pyrite concentrates is impossible without the use of various modifiers in the practice of flotation of sphalerite and pyrite. Such reagents are copper (II), zinc and iron (II) sulfates in an alkaline lime environment. Therefore, studies were carried out to float sphalerite and pyrite in an alkaline lime medium with the addition of one of the indicat-ed sulfates to the mineral flotation operation. The effect of each of the sulfates of copper (II), zinc and iron (II) on the flotation of sphalerite and pyrite was studied during flotation of the mineral with butyl xanthate and dithiophosphate at pH = 8, 10, and 12. The aim of this work was to study the effect of sulfhydryl collectors in the presence of copper sulfates , zinc and iron for flotation of sphalerite and pyrite with a size class (-0.074 + 0.044 mm) from one of the Rus-sian deposits.
