### eddy-current separator technology as a novel approach to

Nov 01, 2004 Abstract. A qualitative test program to study placer gold nugget recovery using an eddy-current separator was sponsored jointly by the University of Alaska and Eriez Magnetics. Various gold nuggets from Alaska, ranging in size from 6.4 to 63.5 mm, were tested. All tests were performed using an Eriez Laboratory ESC, Model REA, fitted with a 2,000-gauss, surface field-strength magnetic rotor
