froth flotation of feldspar

Froth Flotation - Purdue University

Process: The frothing technique is done with a soda carbonator and a mixture of 1 ml/L glacial acetic acid and 1 g/L lauryl amine in 1 liter pure water. The lauryl amine dissolves better in the glacial acetic acid and keeps the pH ~5. This solution is then mixed with 10 liters water and then carbonated.
