The flotation is done in large (10–100m 3) cells whose principal functions are to provide: clouds of air bubbles to which the copper minerals of the pulp attach; a means of overflowing the resulting bubble–copper mineral froth; and a means of underflowing the unfloated material into the next cell or to the waste tailings area.
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.
In this process, the ore initially is crushed to about 1.9 centimetres (0.75 inch), combined with water, and ground to less than 0.1 millimetre in a ball mill. The finely ground particles and water form a slurry that flows from the mill to flotation cells or tanks, where, in the presence of selected chemical reagents that create a suspension of ...

The paper highlights the features of constructing a model of a wet semi-autogenous grinding mill based on the discrete element method and computational fluid dynamics. The model was built using Rocky DEM (v. 4.4.2, ESSS, Brazil) and Ansys Fluent (v. 2020 R2, Ansys, Inc., United States) software. A list of assumptions and boundary conditions necessary for modeling the process of wet semi ...
Gangue minerals, once separated by mineral dressing processes of (most of) the valuable ore minerals and dumped in mine tailings may be a significant environmental impact. In particular, oxidation of pyrite, a common gangue mineral, is one of the main sources of acid mine drainage. Re-use. Minerals that were once thought of as gangue, and were dumped, may later find a commercial use.
Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).

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.
