Automatic filter level control by dilution with filtrate ...

Rotary vacuum disc filters have become increasingly popular for taking coal froth concentrates passed directly to the filter thereby eliminating the use of a thickener. To accomplish this, emergency overflows are provided on the filter tanks and if the froth feed overflows, the overflow material must be pumped back to the froth flotation cells. This causes a great deal of difficulty to the ...

Froth flotation - Wikipedia

Froth flotation cells to concentrate copper and nickel sulfide minerals, Falconbridge, Ontario. Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity. Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents. The selective separation of the minerals ...

Application of othe Hyperbaric Disc Filter

Hyperbaric disc filter dewatering of coal flotation concentrates is common place in China, Eastern Europe and Russia. The hyperbaric disc filter uses an air pressure of up to 0.6 MPa, to drive the dewatering process. This additional pressure is able to achieve surface moisture levels significantly less than conventional vacuum filtration. Two detailed studies have been

Froth Flotation - an overview ScienceDirect Topics

The successful industrial practice of froth flotation requires that flotation be analyzed from an interactive systems approach, as illustrated in Fig. 10. The three major components of the flotation system have been discussed in this article and include chemistry, equipment, and operations. Each component has a series of factors that can be manipulated. Essentially, the nature of flotation

Froth Floation Hoffman Lamson Solutions

Froth flotation efficiency is determined by a series of probabilities like those of particle-bubble contact, particle bubble attachment, transport between the pulp and the froth, and froth collection into the product launder. In a conventional mechanically-agitated cell, the volume occupied by air bubbles is low (5-10%), and the bubble size is usually greater than 1 mm. This results in a ...

Flotation cells: Selecting the correct concentrate launder design - Filtration + Separation

12/01/2010  However, the froth carry rate (dry tonnes of concentrate per square metre of froth surface area per hour, t/m2/hr) and froth lip loading (dry tonnes of concentrate per metre of froth lip per hour, t/m/hr) cannot be determined in a laboratory. This is because the froth is scraped during a laboratory flotation test and thus does not exhibit natural behaviour, and it is not
