Effect of frother type and concentration on the water recovery and entrainment recovery relationship

A study was undertaken to determine the effects of five industrial frothers on the relationship between entrainment recovery and water recovery. The e xperiments were conducted using a Batequip rectangular 60-L steel flotation cell that was run in parallel with the first cell in a copper/silver prefl oat rougher circuit. The concentration of the frothers ranged from 2.5 to 8 .4 g/t. The experiments were repeated at three different froth depths. A po wer function was found to fit this relationship with no discontinuity in th e relationship caused by the changes in frother type and concentration and froth depth.
