Several types of chemicals are involved in froth flotation, and several more can be involved. First is the promoter or frother. This chemical simply creates bubbles …

In this situation, it is possible to have too little froth area, making froth removal the rate-controlling step in the flotation process. An extreme example of this occurs where the largest available cells are not suitable due to froth area limitations, yet may satisfy the old lip length rule.

Copper processing is a complicated process that begins with mining of the from copper sulfide ores, in four basic steps 1 froth flotation, 2 thickening, 3 smelting, and 4 electrolysis The froth is poured into large tanks called thickeners.

Froth flotation is an important step in many mineral processing operations. Often, unwant-ed hydrophobic gangue materials such as talc, graphite, serpentine, chlorite, anhydrite and carbonaceous gangue are also recovered in the concentrate. Low levels of Depramin can be

These collect in a froth heavily laden with sulphide particles. The gangue particles are not brought up by the bubbles, but remain in the mass of the pulp. This is the so-called froth flotation. Its variations, acid-froth, agitation- froth, and pneumatic-froth processes are discussed in detail later.

In the process of froth-flotation adhesion is obtained between mineral particles and air rising through a pulp. This temporarily buoyant combination rises, forms a froth, and is removed. The following steps are taken: (a) The ore is ground in water to at least -48 mesh. (b) The pulp thus formed is diluted to between 25% and 45% solids.

A frothing agent, usually employed with a collecting agent, is added to the ore to assist in separating valuable minerals from the undesired or gangue portions of the ore in subsequent flotation steps.

FROTH FLOTATION “So many variables influence flotation that it will be long before every one of them can be investigated and its influence on the process determined.” The froth flotation process was patented by E. L.Sulman, H. F. K. Pickard, and John Ballot in 1906, 19 years after the first cyanide process patents of MacArthur and the Forests.

The last step in the flotation process is creating a strong but short-lived froth by adding frother when the bubbles reach the surface of the slurry. This froth prevents bursting of the bubbles and release of the Cu mineral particles back into the slurry.
