ABSTRACT:
A process for recovering phosphate values from silica-containing phosphate ores is provided. The ore has a particle size in the range of about 0.6 to 1.2 mm and is subjected to selective flotation in the presence of a cationic flotation reagent comprising a di(hydrophobic group) quaternary ammonium salt, wherein each of the hydrophobic groups contain 6 or more carbon atoms and at least one of the groups contains from about 10-20 carbon atoms, in combination with a hydrocarbon oil and a phosphate depressing agent.
