The effect of the feed size distribution on the kinetic parameters in pyrite flotation was studied. The kinetic parameters of the particular sizes were determined as a function of whether other particle sizes were present. From the data, a relation between the pyrite flotation rate and the particle size distributions was obtained. It was shown that the flotation rate constant (k) is a function ...

Interactive effect of minerals on complex ore flotation:

Froth flotation is the most effective industrial method used to separate fine-grained minerals. The main problem of complex ore flotation is the negative effect of interactions among minerals in slurry, leading to variation in surface properties during separation.

2020-2-20  rate of flotation is very low. When the particle size is too large, there is no adhesion on the bubbles. On the contrary, the efficiency in fine coal flotation is high and the flotation kinetics also increases (Gupta et al., 2001). On the other hand, the flotation rate is strongly dependent on grain size for medium sized coal grains.
