Fatty Acid Phosphate Conditioning & Flotation - Plant Practice

The fatty acid flotation process has been used to produce phosphate for decades, yet the chemical mechanism involved has never been thoroughly investigated. A basic knowledge of the process is lacking, and as such, industry has had to develop their own guidelines for the design and operation of conditioning and flotation equipment. These guidelines are the result of many trial and error attempts, and are not by any means universally endorsed. There are almost as many opinions about how to operate a plant as there are practitioners of the art. This paper covers the currently recommended rules for design as viewed by one practicing phosphate metallurgist.
