Abstract

The refractory or low grade cooper domestic sulphide - chalcopyrite ores in Republic of Macedonia are investigated by conventional flotation separation. In the mean time, investigations are directed to the new possibilities of leaching by microorganisms – bioleaching. The paper is result of these technologies and investigations carried out for recovery of in the mentioned ores. The average grade from flotation process as a copper metal concentrate was cca 20-22% Cu, and recovery was up to 90-92%. The average recoveries from leaching were cca 90-93% for copper and the average recoveries from bioleaching were cca 93-95% for copper.
