For example, if 20% of the water entering a flotation cell is carried into the froth, then up to 20% of the fine particles entering the cell will be entrained. The entrainment of coarser particles will be less than 20%, due to their greater ability to drain from the froth.

(Clean Coal) was first crushed using a series of jaw, cone, and roll crushers to reduce the particle size under 1 mm. The particle size distribution and ash content of the lignite sample used in flotation tests are shown in Fig. 1. Following the crushing process, the sample size was reduced to 212 m by grinding in a ceramic ball mill.

AbstractThe effects of size distribution on the flotation behaviour of sphalerite have been investigated in terms of kinetic parameters. In experimental studies, subsamples of a Turkish sphalerite ore were ground for different times using a laboratory ball mill. Timed batch tests were then undertaken using a pilot flotation column and the resulting recovery/time data were used in kinetic

pyrrhotite recovery in the environmental desulphurization process by flotation? Two main approaches are used to improve the fine particle recovery in flotation; to increase the particle size, or to decrease the bubble size. Particle size is increased through several aggregation methods and the aggregated particles are then floated, a

Therefore, it should be noted that the coarse fractions (+0.25 mm) have a high desorption probability during the flotation process and the fine fractions (0.074 mm), with high ash, can easily degrade concentrates through mechanical entrainment during the flotation process (Schulze, 1982, Fuerstenau et al., 2007, Rahman et al., 2012).
