Dewatering of Copper Flotation Tailings: Effect of Feed ...

Jul 19, 2018 · Aqueous slurries’ dewatering using gravity-driven thickeners is an essential unit operation in mineral processing. Thickener feed dilution is often used for enhanced flocculation and sediment compressibility. This work investigated the effect of feed dilution on thickener performance for copper flotation tailings.

Segregation Process of Mixed Sulphide Copper Ore

These are of standard type used for flotation of native copper and sulphide copper minerals. Standard Flotation is used. In order to prevent gangue flotation and concentrate contamination, small quantities of sodium silicate may be useful. If the upgrading of concentrate is difficult, regrind of concentrate can help, previous to new flotation. CONCENTRATE DEWATERING

Copper Sulfide Ore Flotation Technologies - Xinhai

Copper sulfide ore has good inherent floatability, so flotation process is a mature method used for copper sulfide ore separation. In recent years, with the continuous development of copper sulphide flotation technology, many scholars also proposed a series of new principles of mineral processing, such as “collect early, loss early” and “more crushing and less grinding”.

Mineral processing - Wikipedia

Froth flotation is an important concentration process. This process can be used to separate any two different particles and operated by the surface chemistry of the particles. In flotation, bubbles are introduced into a pulp and the bubbles rise through the pulp.

Palabora Mining Company Ltd

Certain sections are used for wet grinding marginal ore to below 0.3mm, followed by a copper flotation process similar to that used for the underground ore. Concentrate is pumped to the dewatering plant, while magnetite is removed from the tailings before thickening and pumping final product to Foskor for phosphate flotation.
