Copper oxide ores with high clay content and fine particle size distribution pose major challenges for conventional flotation. In this study, a low-grade copper ore (0.5% Cu) obtained from drill core ...
A locked cycle test using optimized flotation conditions derived from flowsheet development testwork returned a copper concentrate grading 24% Cu, 1.2 g/t Au and 178 g/t Ag at a 91% copper recovery, ...
