#0183;#32;Six flotation tests were conducted using the coppergold ore and its mixtures with quartz, clay minerals and gypsum. Fig. 1 shows the mass recovery as a function of water recovery from these tests. As can be seen, flotation of the ore or baseline resulted in a 5% mass recovery and 31% water recovery at the completion of flotation.
