the effects of the key variables on the selective flotation of mt. weld phosphate ore were studied with the aim of optimizing the flotation process to yield a concentrate of the following specifications: >36% p 2 o 5 <3% fe 2 o 3 p 2 o 5 fe 2 o 3 + al 2 o 3 >10 at a p 2 o 5 recovery of >70%. the main difficulty was to reduce the iron content in the apatite concentrate to the level required.
flotation uses a chemical reagent to make one or a group of minerals adhere to air bubbles for collection. chemical reagents include collectors frothers antifoams activators and depressants. the type of reagent used depends on the characteristics of a given ore. a typical flotation process sometimes requires desliming.
