PLANT FLOTATION MACHINES IN BANKS - 911Metallurgist
The conditioned pulp is run into a flotation cell, which is crudely a box with a stirrer, and a means of introducing air. Typically, the cell might contain 15-30% by volume of entrained air with bubbles ranging mainly from 0.1 to 5mm in diameter; the “pulp density” might be 25-40% of solids having a particle size ranging from 10-100um.
