Abstract
The practice of benefication of copper-zinc ores has established that the production of high-quality zinc concentrates is impossible without the addition of sphalerite and pyrite modifiers to various flotation operations. This article present the result of study of the effect of copper (II), zinc and iron (II) sulfate on the froth flotation of sphalerite by sulfhdryl collectors. Typically, it is achieved through optimisation of flotation circuits, installation of modern equipment and changing the flotation reagents modes. Therefore, the floatability of sphalerite in an alkaline lime medium was studied with the addition of one of these metal sulphates to the mineral flotation operation. The effect of each of copper (II), zinc and iron (II) sulphates on the floatability of sphalerite was studied by flotation of the mineral and by potassium butyl xanthate and sodium dibutyl dithiophosphate at pH = 8, 10 and 12.
