Solutions for Direct and Reverse Flotation. Phosphate ore is the most important source of phosphorus in fertilizers. To supply the phosphoric acid plant with phosphate, a high grade of phosphorus is essential, as well as reduced levels of impurities such as magnesium, iron and aluminum oxides.5 Types of Phosphate Froth Flotation Process,Phosphate Reverse Froth Flotation Process. The reverse flotation process is to adjust PH of the slurry to 5.0 ~ 6.0, inhibitphosphate mineral by adding inhibitors, and then enrich carbonate in the foam with a selective collector. The process is mainly suitable for calcium-magnesia colloidal phosphate ore with high calcium and magnesium content,COMPOSITIONS AND METHODS FOR REVERSE FROTH FLOTATION,May 25, 2018· In reverse froth flotation of phosphate ores, increasing the dosage of a fatty acid collector tends to increase the % P 2 O 5 in the concentrate (% grade) at the expense of % P 2 O 5 recovery of concentrate. We have found that the same is true of the sulfonated fatty acid and/or sulfonated fatty acid salt collectors, i.e. in reverse froth,

Phosphate flotation - W. R. Grace & Co.

Mar 22, 1983· This invention is directed to a novel process for the flotation of phosphate ores, to recover phosphate ore as the concentrate. It is a type of flotation known as "reverse flotation", since the tailings (quartz or silica particles) are floated, and the desired ore, namely phosphate rock particles, sink and become the concentrate.reverse flotation of phosphate - AIPS,Reverse Flotation Of Phosphate.
