The Adsorption of Cu Species onto Pyrite Surface and Its
The adsorption of Cu species onto pyrite surface and its effect on flotation were investigated by using microflotation tests, first-principle calculations, and XPS surface analysis. The results indicated that the flotation of pyrite appears to be activated with CuSO4 only at alkaline pH, while being depressed at acidic and neutral pH. The adsorption of copper …

Chalcopyrite (Cu) Sphalerite (Zn) Separation by Flotation
Copper 3.78%. Sulphur 42.38%. Zinc 12.45%. Gold 0.01 oz/ton. Iron 32.84%. Silver 1.50 oz/ton. Insoluble 8.50%. In order to meet smelter requirements it is desired to produce at least a 20% copper concentrate with not over 8% zinc. The copper is present principally as chalcopyrite in extremely close association with both the sphalerite and pyrite.

Features and Flotation of Complex Cu-Pb-Zn Sulphides
Problems arising during flotation of complex Cu-Pb-Zn sulphide ores are in general of geological origin. The features of these ores are reviewed, stressing that mineralogical studies extending to process mineralogy are prerequisite for a consistent flotation process. Some examples affecting flotation are given.
1 Froth Flotation – Fundamental Principles
no flotation can occur. Contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in Figure 5. Figure 5: Simplified schematic of a conventional flotation cell. The rotor draws slurry through the stator and expels it to the sides, creating a suction that draws air down the shaft of the stator.
