The fully mixed kinetic flotation model expressed in Eq. (12.34) has been used primarily in analysis of mechanical cells and flotation columns. Some of the newer cell designs aimed at increasing the flotation rate fall into a category that can be described as "reactor–separator" designs. A feature of the reactor part is a high concentration of bubbles.

flotation models are linked. For example, a laboratory test conducted on a drill core sample, intended to represent a portion of the orebody, is conducted at a specific grind (represented by a P 80). However, when that ore is actually processed through the plant it may well be (and in many cases most likely will be) at another P 80 ...
