Description: ABSTRACT: This report examines methods of obtaining metal recoveries efficiently and quickly from open pit mine waste.  Tests were done and a prompt method was found.  The procedures involve crushing and sizing, then flotatio of the fines and leaching the coarse fraction. These processes may cost more than conventional methods but they also result in additional profits.
