K. Rahal et al., Effect of frother type and concentration on the water recovery and entrainment recovery relationship, MIN MET PR, 18(3), 2001, pp. 138-141
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.
