ABSTRACT:
A method for reclaiming an aqueous emulsion useful as a metal-working lubricant/coolant which is contaminated with particles of at least one metal comprises contacting the contaminated emulsion with at least one metal solubilizing agent at metal solubilizing conditions to solubilize at least a portion of the metal particles. The thus contacted emulsions have improved suitability as a metal-working lubricant/coolant relative to the contaminated emulsion.
