Abstract
Coarse silica flotation from intermediate pebble (IP) product has been carried out a pilot plant Dual Extraction Column (DEC) at an operational phosphate mine in Central Florida. The solids feed rate ranged from 4.16-5.3 TPH while the amine dosages ranged from 0.32-0.93 lb/T. The optimum amine dosage when using recycled process water was determined to be 0.6 lb/T. With a feed containing 40-45 BPL and 38-45% insol, the results show that the IP can be upgraded to 56-61 BPL and insol of 16-22% at 85-90% BPL recovery. The results show that the DEC is an effective device for flotation of coarse silica from the IP. The advantages of upgrading the IP prior blending with the pebble are presented and discussed.
