| Abstract: | In order to upgrade the mineral processing index of a low-grade copper-nickel sulfide ore, a bulk flotation flowsheet with optimized reagent scheme was adopted after a thorough study on ore properties and on-site problems. With the feed ore assaying 0.714% Ni and 0.446% Cu, a bulk concentrate was finally produced with Ni grade and recovery of 6.45% and 69.40%, and Cu grade and recovery of 5.04% and 86.76%, respectively. This approach has been applied successfully into industrial practice. |
