Copper is most commonly present in the earth's crust as copper-iron-sulphide and copper sulphide minerals, for example, chalcopyrite (CuFeS2), bornite (Cu5FeS4) and chalcocite (Cu2S).
2. Flotation Cells. Flotation cells are large tanks where the separation process happens. The ore slurry is mixed with reagents, and air is blown into the mixture. Different designs of flotation cells exist, but they all serve the same purpose: to create bubbles that the copper minerals can attach to and float to the surface. 3. Air Bubbles

Froth Flotation machine plays an indispensable role in the mineral beneficiation process, flotation is susceptible to a number of factors during the process, including grinding fineness, slurry concentration, pulp pH, pharmaceutical system, aeration and agitation, flotation time, water quality and other process factors. The factors that …
Flotation Cell Product Introduction Flotation machine is the also called flotation concentrator, which refers to the mechanical equipment that completes the flotation process. In the flotation machine, the ore pulp treated by adding reagents is stirred and aerated to selectively fix some of the ore particles on the bubbles.
In the mineral processing field, flotation techniques have witnessed significant trends and best practices that are shaping the industry. One prominent trend is the increasing reliance on digitalization and data analytics. Mining companies are investing in advanced sensors, data integration, and machine learning to gain deeper insights …

A flotation bank is a serial arrangement of cells. How to optimally operate a bank remains a challenge. This article reviews three reported strategies: air profiling, mass-pull (froth velocity) profiling and Peak Air Recovery (PAR) profiling. These are all ways of manipulating the recovery profile down a bank, which may be the property being …
