Sentence examples for minimal froth depth from inspiring English sources

The flash flotation machine on this particular circuit recovers fast floating well liberated particles, with a minimal froth depth and short residence time; while the rougher column has a very deep froth and long residence time.

In all experiments, the froth depth was shallow and the froth recovery factor (R f) was assumed to be 1.

The rejection of entrained particles, in this case, inorganic ash forming minerals, depends on froth depth.

The column was filled with water and stabilized at required froth depth.

If there is no enough froth depth, these particles will be carried along with the clean coal and thus the quality may be affected and the froth depth of 600 mm is optimized for further experiments.

At the same time the ash content in the clean coal is reduced gradually as the froth depth increases.

Experiments were developed as a 2 × 2 factorial design, in which the effect of superficial air rate (1.2 1.8 cm/s) and froth depth (2 4 cm) on the froth transport for a two phase (air water) system was characterized.

The effect of gas distribution profile on limestone grade was found to dwindle as froth height was increased; changes in limestone grade ranged between 0.47 and 2% for a froth depth of 10.1 cm while those for a froth height of 6.3 cm ranged between 1.40 and 5%.

It is found that the second order rate constant, k2 is negatively correlated with the froth depth and positively correlated with the air flow rate.

Electrical conductivity, an intensive property of materials, has been used in flotation for measuring important process variables such as froth depth, bias rate, solid and gas holdup.

The factors affecting the treatment effectiveness, such as the froth depth, air flow rate, pulp density and impeller speed are studied.
