Column Flotation • Theory and Practice

conventional mechanical cells. Column flotation, invented in the early sixties, proved to be a better alternative to the conventional cells. The main advantages of column flotation are : i) improved recovery, ii) higher grade, iii) lower capital and operating costs, iv) less wear and tear due to absence of moving parts and v) requirement of less floor space. Columns of varying design are in ...

Flotation of coarse particles in a counter-current column cell

1991-02-01  The effect of particle size on the flotation of coarse particles is analyzed. It is concluded that turbulence and the presence of the froth layer are detrimental to the recovery of coarse particles during conventional flotation. A counter-current column cell is proposed to avoid these two factors. In this column, a net upwards flow of water is prevalent, such that no froth is allowed to form ...
