This is a very important measurement for the flotation operator. Some minerals like Iron pyrite will not float well in an alkaline flotation circuit. An alkaline solution is also slightly caustic, this will help clean the surface of the mineral. This strengthens the bond between the collector and the surface of each mineral particle.

2.1 Froth flotation process. Froth flotation is extensively used to enrich sulfide minerals (galena, chalcopyrite, sphalerite, molybdenite, and pentlandite) as well as non-sulfides such as phosphate minerals, iron ores, and fine coal [1, 2].The mineral ore is ground to fine particles of typically 10 to 100µm in diameter and mixed with water to create a slurry.
