Abstract
Copper mine "Cerovo"- East Serbia as well as the other ore bodies in its
vicinity contain a significant amount of oxide copper minerals in their uper
layers (>40%). Processing of such mixed ores by the existing concentration
technologies leads to a substantial copper losses (<60%). Reduction of "oxide
copper", by acid leaching prior the flotation concentration, can increase the
overall copper efficiency up to more than 70% in the single-stage leaching,
achieving an efficiency in the flotation concentration stage higher than 75%.
Based on the performed experimental results the flow sheet for processing of
the mixed oxide-sulphide copper ore is proposed.
