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

Anionic Rougher-Cleaner Flotation. 02-151-200Final. Abstract. The Crago process has been used almost exclusively for about 50 years to recover flotation concentrate from Florida phosphate ores. Although the process has been able to produce high-grade concentrate from all manner of feeds, relatively high costs were incurred because of the need

2015-11-4 · The recovery of liberated grains of sphalerite into the rougher and scavenger concentrate increases linearly with flotation time. Overall 15% of the liberated grains of sphalerite are recovered in the combined rougher scavenger concentrate. Liberated pyrite and non-sulphide gangue minerals are efficiently rejected out the scavenger tail stream
