Different Types of Flotation Cells
However, today "flotation" is the principal method of mineral processing throughout the world. Capacity of the first flotation mill was only 50 tons of ore per day. Now more than 100 different minerals are commercially recovered by flotation and some mills process as much as 50,000 tons of ore every 24 hours. CHANGES IN FLOTATION …
Flotation Rate
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.
