· Therefore, the life cycle of water used for flotation should be considered in the designing and operation of flotation plants. Once the most important step is identified in the circuit, e.g., the key points in enhancing water use efficiently, corresponding methods can be derived for water managements.

To perform a flotation process the mineral is finely ground (particle sizes between 50 and 150 μm), then the ground mineral is mixed with water in a container called a flotation cell. Afterward it is introduced into the flotation cell via an external medium and small bubbles of air produce a pulp (metallurgical pulp) where mainly particles, water, and air coexist.

Even if the flotation process is very efficient, mineral liberation is not perfect. There are always some middling particles in which gangue and valuable minerals are still combined physically. If these particles go into the concentrate,

· In froth flotation, a depressant is a reagent used to inhibit the flotation of certain minerals or undesirable components in the ore, allowing for the selective recovery of valuable minerals. Depressants work by selectively adsorbing onto the surface of specific minerals, making them less hydrophobic and less likely to attach to air bubbles during

· Flotation. The FLOTATION PROCESS is one of the commonest methods of extracting the valuable minerals from certain classes of ores, and it is generally more efficient as regards the recovery of the minerals than any other process applicable to the treatment of similar types of ores.

From the perspective of a plant metallurgist or operator, the role of a flash flotation cell in a concentrator is to remove any liberated valuable mineral and/or any coarse composite particles rich in the target valuable mineral; and this has also been the long held belief of the authors.
