D.Sc. (Chemistry)
The Phosphate Development Corporation (FOSKOR) recovers apatite from foscorite ore by a process of froth flotation. Four reagents are used viz. sodium hydroxide, water-glass, nonylphenol tetraglycol ether (EMU) and a fatty acid. The fatty acid is mainly composed of a mixture of oleic and linoleic acid in a ratio of 1,2:1. The aim of this study was to investigate the influence of the first three above-mentioned reagents on the adsorption of oleic, linoleic and linolenic acids on apatite and The Phosphate Development Corporation (FOSKOR) recovers apatite from foscorite ore by a process of froth flotation ...
