Flotation is still the most applied mineral processing technology in the separation of minerals. For high flotation recovery, particles should securely attach to bubbles and stay stable during flotation. The most critical parameter affecting bubble-particle aggregate stability is particle size.
Column flotation cells, like mechanical cells, are used to perform mineral separations. Column cells do not use mechanical agitation (impellers). Instead, mixing is achieved by the turbulence provided by the rising bubbles. Columns are mostly used to produce final grade concentrates because they are capable of high selectivity.

The graphs show platinum group metals as PGMs and gangue recovery with flotation time at six different air rates measured as cubic meters of air per minute per cubic meter of pulp. PGM concentrate …
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.
eriez has developed a flotation cell that uses fluidized water to enhance flotation of coarse particles. More than 40 units have been sold in industrial minerals, and we are …
The methods of extracting gold from quartz vein ore, sulfide ore, polymetallic gold-bearing ore, gravity separation, flotation, and cyanidation can all achieve high recovery rates.
In recent years, a great deal of work has been done to quantify the plant influences of the various factors of the three major flotation components. This work has required that valuable recovery vs time of flotation be measured in small-scale batch laboratory flotation cells capable of handling feed charges of 500–2000 g. These smaller cells ...
Flotation machines constitute the basic equipment for useful minerals recovery from non-ferrous ores and other raw materials by flotation. Flotation Cells (Froth Flotation) were developed to separate and recover high-value Sulphide ores from low-grade ore bodies.
