The flotation process is characterized by the following: The two resultant products, concentrate and tails, need to be evacuated properly. The most widely used flotation machines can be broadly classified into ‘mechanical’ and ‘pneumatic’ depending on various factors. The former use impellers or rotors, which are absent in the latter.This technology is expected to change the present situation of low-level intelligent control of the coal flotation process, and plays a key role in improving the monitoring level, optimising operation, and processing intelligent control of flotation production.

The use of machine vision to predict flotation performance
Machine vision has been proposed as an ideal non-intrusive instrument to obtain meaningful information relating to the performance of the froth phase of flotation for the purposes of process control. Many attempts have been made to use machine vision to predict performance factors such as mass recovery rate and concentrate grade. These Abstract.

Modelling for froth flotation control: A review ScienceDirect
Introduction. Froth flotation is the largest tonnage separation in mineral processing by which valuable mineral is separated from waste rock. Advances in control and optimisation of the froth flotation process are of great relevance since even very small increases in recovery lead to large economic benefits (Ferreira and Loveday, 2000, Fault condition detection for sulfur flotation process based on texture unit distribution [J].

Effective treatment of emulsified oil wastewater by the coagulation
The coagulation–microbubble flotation device could efficiently demulsify and degrease the emulsified oil wastewater with pH of 6.7–6.9, flow rate of 0.250 m 3 h −1, and oil content of 3000–5000 ppm. The resulting COD and turbidity in the treated effluent after coagulation–flotation process were 30–60 mg L −1 and 100–120 NTUAlthough pneumatic flotation * There is no more production of these cells in the market machines e.g., Imhoflot TM,and Jameson TM were invented in the 1980s, their application in mining(PDF) Froth flotation process and its application ResearchGate

Froth Flotation Process Detailed Explanation with
Flotation is the process of separation of beneficial minerals from a mixture by creating froth on which minerals separate out. This is a method of mineral processing in which different minerals are separated selectively. The The FLOTATION PROCESS is one of the commonest methods of extracting the valuable minerals from certain classes of ores, and it is generally more efficient as regards the recovery of the minerals than any other process applicable to the treatment of similar types of ores. The metallic contents of the minerals are recovered Flotation 911 Metallurgist

SELECTION OF MECHANICAL FLOTATION EQUIPMENT AusIMM
Mechanical flotation cells can be broken down into two broad categories based on how air is introduced to the cell. In a self aspirated flotation cell air is introduced to the slurry,the vacuum created by the rotorusing . In a forced air flotation cell air is generated external to the cell by a low pressure blower,,and pumped down theThe mixed flotation process is a commonly used process in the flotation of polymetallic sulfide ores. First, all the useful minerals are mixed and floated, and then the useful minerals in the mixed concentrate are separated one by one. This process is suitable for useful minerals grade comparison.
