flotation process for copper ore in niger

smelter. Froth flotation is part of a copper beneficiation process in which finely ground ore is placed in aerated tanks that contain a water-based solution from which a copper-sulfide-rich froth is recovered through the use of a combination of physical and chemical interactions. The remaining non-ore minerals

Froth Flotation Process Detailed Explanation With

Thus the sulphide ore comes on the top with the froth and oil. The remaining gangue particles which did not dissolve in oil settle down. The foam is removed and taken for further processing. Thus the minerals are separated by the froth -flotation process. This method is extensively utilized for Copper sulphide, lead sulphide and Zinc sulphide. Learn More

Development of copper recovery process from flotation

Jun 15, 2018 The total copper recovered from its ore through flotation process is about 56% [6,18], which indicates that the flotation tailings still contain valuable copper components such as chalcopyrite. In addition, old flotation tailings sometimes have a higher copper grade (0.2–0.4%) than that of low‒grade ores (0.2‒0.3%). Learn More

Froth flotation Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century. Learn More
