PSG method for the simulation of carbon particles accumulation in the flotation process

Abstract

Abstract Carbon agglomeration on the surface of gaseous bubbles in the flotation process has been modeled in this paper. The calculations were based on the PSG method and performed for five strictly defined size groups of carbon particles (M=5) for initial sizes 100-400 µm, and mixing energy ε = 0.01 [m2 s−3]. The analysis of the obtained results revealed that the process was much faster for particles with bigger initial size 300 and 400 µm. In this case the time needed for the removal of particles in particular size groups was shortest. It was observed for all analyzed cases that the process was most dynamic in the initial phase, whereas at the end of it the agglomerations considerably lowered because of the decreased number of particles in specific groups.
