Figure 1 is a generalized diagram of a conventional copper flotation plant from the point where ore first enters the circuit to the production of concentrate and tailings. To prepare ore for the flotation process, run-of-mine ore, which may contain from about 2 to 5 percent water, by weight, when mined, is

Flotation depends on the fact that the grains of some minerals, and especially of metals, differ in the degree to which their surfaces can be wetted by a suitable solution. The powdered product of grinding the ore is fed into a series of tanks called flotation cells which are filled with a solution containing various oils capable of forming …

Over the past few decades, the need to process more minerals while lowering capital costs has led to an increase in the size of flotation cells, e.g., 0.03 m3 to 1000 m3. However, this increase has created new challenges in the operation and design of industrial flotation cells, particularly in terms of froth removal, because the distance …

This will result in completely digital communication between instrumentation and base level control systems at source, and has already enabled the decentralisation of pulp level and air flowrate base level control systems. This has also allowed for better integration of base level control during flotation cell design (Laurila et al., 2002).

The process choice of copper ore flotation is determined by the raw ore properties. Meanwhile, there are many determining factors for the copper ore flotation process, like the mineral disseminated particle size, the associated relationship with quartz rock, and the gangue mineral types.

The conditioned mineral slurry is then processed in flotation cells, which are essentially agitated tanks into which finely-dispersed air bubbles are introduced. The desired hydrophobic mineral will then attach to the air bubbles and float to the top of the flotation cell, where it will be skimmed off as a mineral-laden froth.
