Effect of particle shape on the flotation kinetics of fine

2018-9-10 As is known, the floatability of −0.25 + 0.125 and −0.125 + 0.074 mm size fractions are usually better than that of −0.71 + 0.5 and −0.5 + 0.25 mm size fractions. For the coal particles owning a better floatability, the influence of particle shape on their flotation behavior becomes less obvious.

Effect of particle size on magnesite flotation based on

2020-10-1 Owing to the lower probability of collision and attachment between fine particles and bubbles, it is difficult for fine particles to float into the froth products. Therefore, the effects of particle size on the flotation kinetics have been extensively studied [16,18,23,24]. However, it is almost impossible to accurately predict the flotation results when the feed particle size varies greatly.

Kinetics of flotation. Order of process, rate constant

2016-12-27 , distribution of flotation rate constant f(K) and order of flotation kinetics n in Eqs. 6 and 7 can be determined from the experimental data of R versus t. In the present article, it is sought to review kinetic models based on these three parameters, for instance, f(K) n and R∞, with a focus on the description of the

Kinetic models can be used to characterize the flotation process. In this paper, three primary parameters, namely, distribution of flotation rate constant f(K), order of flotation process n and ultimate recovery R∞ are presented to perform analysis of flotation kinetics. The flotation rate constant f(K) is a function of both the size and hydrophobicity of particles.

Effect of galena grain size on flotation kinetics

2016-1-13 Laboratory tests of relationship between kinetics of flotation of pure galena smaller than 38 μm in size and concentration of potassium butyl xanthate show that flotation rate undergoes considerable reduction when mineral grains are under 18 μm in size. Size grades below 18 μm show the slowest flotation rates that are nearly equal at the collector concentration of 0.5 mg/l.
