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.
PH Modifiers. The role of pH modifier and the dosage affect flotation . From test results, it was confirmed that sodium silicate and other chemicals can be be used with depressant and dispersant could adjust the pH of pulp . Flotation efficiency using pH modifier is better than that using lime in the alkaline conditions (pH 9.5–11).
