The old tailings from mine dumps in Namibia contain not only copper but also precious metals and other metal values, such as lead zinc, which should be recovered to supplement the production of ores. X-ray fluorescence (XRF) analysis showed that it contained 0.8% Cu, 40 ppm Au, 60 Ag, 0.9% Pb, 0.7% Zn 1% Fe. Batch roughing tests were conducted investigate effect pH, collector (PAX) dosage, sulphidiser (Na2S) dosage on recovery (Ag Au). Results for flotation test work values depends three operating variables. Maximum recoveries Cu (52%), Ag (53%) Au (44%) achieved at pH 10.5, PAX 47 g/t, Na2S 109 g/t 12-minute residence time. Testwork is still progress improve copper, gold silver.
