Cold-reduced flat-rolled low carbon steel strip is surface cleansed of ferromagnetic contaminants including iron fines, iron oxide particulate and associated debris which result from gauge-reduction operations. Such ferromagnetic contaminants are permanently removed from the strip steel hot-dip galvanizing system by dynamically concentrating such contaminant which are flushed to a magnetically-assisted particle separation container, formed from paramagnetic sheet material, which retains such contaminants, while cleansing solution at a desired purity level, is returned to the surface cleansing system; with sedimentation tank means providing for diminishing waste disposal concerns by separating sludge and recycling liquid.
