Froth flotation - Wikipedia

Froth flotation is a process for selectively separating 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.

The Importance of pH in Flotation

In flotation, pH control is a vital method to control selective mineral separation. A standard depressant that is used is an Alkali. An Alkali is any substance that when mixed with Acid will neutralize each other and form a new chemical substance called a BASE. This is very important. The ore may be either alkaline or Acidic. To have a positive control over flotation, it is necessary to be ...

Simulation in Mineral Processing | SpringerLink

Abstract. A technique for simulating a continuous flotation circuit from batch test data is described and demonstrated. Because the simulation is based on a kinetic analysis of the batch data, a method for accurately collecting rate data from a batch test is also described; and based on the kinetic results, it is shown that an optimum time can be specified for a flotation stage.
