ABSTRACT:
The present invention relates a process for simultaneously preventing formation of slime stabilized foam and decreasing reagent consumption in a phosphate beneficiation flowsheet comprising adding an effective amount of a polymer to a rougher feed slurry and/or a cationic feed slurry wherein the polymer flocculates slime, adding an effective amount of a collector and removing the flocculated slime by flotation.
