Too coarse ore particles (greater than 0.1mm) and very fine ore particles (less than 0.006mm) do not float well, and the recovery rate is low.. In the flotation of coarse particles, due to the larger weight, the shedding force of the ore particles increases.So, you need: (1) Use a sufficient amount of the most effective collector.

The primary difference in flotation cells is the two ways of introducing the gas. Gas introduced into the bottom of a cell and dispersed into a water in the form of very fine bubbles will rise to the top of that cell and carry with it suspended solids and entrained oil. Additional frothing can be created by injecting surfactants or other water ...
