| Abstract | The flotation of oxide copper ore with sodium oleate was investigated to determine the optimum pH and dosages ofchemical reagents. From the mineralogical analysis using X-ray diffraction, malachite was the major mineral and the gangueminerals were mostly silicates such as quartz and kaolinite. As a result this ore was characterized as oxide copper. This resultrelated well with the chemical analysis using XRF which indicated that copper was the main element with some minorconstituents. Oxide copper ore flotation with 800 g/ton sodium oleate at pH 9 yielded 14.4% Cu with 83.3% recovery in arougher circuit. To enhance the flotation performance, in terms of %Cu, optimum dosages of sodium silicate, quebracho, andpine oil were examined. At the optimum dosages, the grade increased to 20.1% Cu with 76.4% recovery. To upgrade the rougherconcentrate, sodium oleate was added in the cleaner stage and without any reagents added in the recleaner stage. The bestperformance was achieved in this rougher-cleaner-recleaner circuit with 70.7% recovery of 26.9% Cu. This finished concentratecomplied with the copper market standard. |
