Flotation machines can be classified into two main categories: mechanical and pneumatic. Each type has its advantages and disadvantages, depending on the specific application. 4.1 Mechanical Flotation Machines. Mechanical flotation machines, also known as conventional flotation machines, are the most common type used in industry.

Unfortunately, the conventional flotation cell achieves high recovery only in limited size ranges. For example, a sulfide ore might float very well at 90 to 120 microns, but not at 50 or 150 microns. The research to date has identified two main reasons for the upper limit on floatable particle sizes.
