sulphide flotation recovery froth floation

FROTH FLOTATION : RECENT TRENDS Flotation of

flotation of sulphide minerals. It is established that xanthates decompose in acidic environment and hence, results lower flotation recovery. Through proper control of pulp pH, one sulphide can be selectively floated from other. As regards other reagents used in sulphide flotation, depressants like

Sulphide Flotation - an overview | ScienceDirect Topics

Where there is no constraint on concentrate quality, high gold and sulfide flotation recoveries are achievable to the extent that a discardable gold flotation tail is possible (Bax and Bax, 1993; O'Connor and Dunne, 1991). Cleaning-circuit configuration, either single or two stages of cleaning, and cleaner residence time are related to the particle size of the sulfides in the flotation feed and the presence or

How to improve Lead Pb Recovery - Froth Flotation

Adding increased air rate in flotation should increase the recovery. Floating (collecting froth) for a longer time should increase the recovery. If the froth looks very weak (bubbles breaking easily) then you may want to add one or two more drops of frother to help make the froth stable

Effects of impeller speed and aeration rate on flotation

solid entrainment is linearly related to the water recovery regardless of aeration rate and impeller speed, and the higher sulfur recovery at the aeration rate of 2 and 4 L/min for the impeller speed of 1 500 r/min is considered to be the contribution of true flotation. Finally, the sulfur recovery flux is correlated with the bubble surface area flux based on the froth image at the different aeration rates and impeller
