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,Performance Laboratory Flotation,Laboratory flotation machines are simplified and smaller flotation equipment. These laboratory machines are used in metallurgical tests, mainly focusing on reproducibility and achieving similar performance to industrial flotation operations . Generally, there is a trade-off between these goals.from laboratory flotation tests to the simulation of an,,Deinking chemistry performance: from laboratory flotation tests to the simulation of an industrial pre-flotation line D.
