Froth flotation is the most widely used phosphate ore separation process. Because of the nature of the phosphate ore such as mineral types and content disseminated particle size its separation difficulty and flotation types varies. Phosphate ore is divided into siliceous phosphorite calcareous phosphorite and siliceous phosphorite according to the chemical composition of the minerals.The froth flotation types differ from different types of phosphate ore greatly. The following is a brief introduction to 5 common types of phosphate ore forth flotation process.

Froth flotation process can be divided into one stage froth flotation and two stages froth flotation also known as stage froth flotation. So how do you choose the froth flotation process according to the stage Generally the selection of froth flotation stages mainly depends on the embedding features of useful minerals.

Flotation can be used for a number of materials by adjusting the chemicals. At Newmont it is used for copper recovery and in a very limited number of cases for gold processing. We introduce air bubbles to the slurry while it is in small tanks called flotation cells. We add some chemicals to the slurry to assist the process.

Nov 21 2018nbsp018332Flotation is usually used by large scale miners but can also be applied in small scale operations. It is a process that works best for processing complex ore types especially ores that are difficult to process using gravity methods. In flotation a mixture of slurry crushed ore and water and frothing agents are added into a flotation machine.

Flotation columns comprise a tall tank in which the separation between froth and pulp occurs an aeration system a pulp level control system a wash water system a discharge barometric leg and a set of control instruments besides pipe connections for feed concentrate and tailings. Figure 1 illustrates a typical column.

Flotation Columns Getting The Most From Fine Ores Outotec

Flotation Columns Getting The Most From Fine Ores Outotec

The column is fed with ore pulp in its upper third portion and at the lower section air is injected at high velocities. This causes the pulp to flow down against a swarm of rising air bubbles. This counter-current flow promotes the suspension of particles in the pulp. In addition the energetic injection of air provides for the generation of small bubbles and promotes the contact of these bubbles with the ore leading to the collection of hydrophobic particles.

Physically column flotation is controlled through adjustments in the pulpfroth level in the flow rate and pressure of air and in the wash water flow. Besides these physical aspects the reagent scheme can also be changed to achieve the desired performance. The correct combination of all these factors for a specific ore provides the optimized concentration of minerals.
