Advanced flotation process control system at a base metal concentrator

Flotation experiments were conducted in a Denver type agitated flotation cell at the rougher stage. The experimental results showed that increasing the pH (from 8 to 10) at low agitation rate (1000 rpm) enhanced the recovery from 80.36% to 85.22%, while at high agitation rate (1200 rpm), a slight declination occurred in the recovery.

Predictive modelling aims to define optimized process parameters for the concentrator plant to accommodate the variability of the ore feed characteristics. ... (cleaner) flotation cells. 1800 rpm and an airflow rate of 3 l/min were used. The Aerofloat 208 (100 g/t for XI and V and 130 g/t for C1 and C2 ores) was used as a collector and …

The future of flotation

Unfortunately, the conventional flotation cell achieves high recovery only in limited size ranges. For example, a sulfide ore might float very well at 90 to 120 microns, but not at 50 or 150 microns. The research to date has identified two main reasons for the upper limit on floatable particle sizes. First, coarser particles tend not to have as ...
