A new high-capacity flotation technology, the StackCell®, has been developed as an alternative to both conventional and column flotation machines. This technology makes use of a pre-aerated, high-shear feed canister that provides efficient bubble-particle contacting, thereby substantially shortening the residence time required for coal flotation.

The flotation behavior of Xixia andalusite was studied with different collectors. The tests were conducted with a pure andalusite sample in micro-flotation cell and then with an ore sample in a mechanical flotation cell. The surface charge was measured on pure andalusite sample and the isoelectric point (IEP) was found to be pH 5.2.

Froth flotation is a process for selectively separating of hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

Direct flotation of pyrochlore from its ore can be carried out at acidic pH using 1-amidoethyl-2-substituted imidazolines of the formula ##STR1## wherein R and R' are independently alkyl or alkenyl of 8 to 22 carbons, or their salts. In the presence of large amounts of carbonate in the ore, the pulp is acidified with hydrofluoric acid, fluosilicic acid, or their acid reacting compounds.

Flotation behaviour in plant practice A typical mineral balance of the rougher-scavenger circuits is given in Figure 1, based on the average of two plant surveys conducted in 1990.

First let's change the amount of the Flotation Depressants used. The valuable mineral that isn't liberated from the unwanted mineral will begin to be depressed along with the waste. For the floatation operator, the change that will become most apparent is, that the color of the froth will begin to reflect more of the wanted mineral's color.
