| Abstract: | Flotation tests were conducted for a high-sulfur lean Cu-Pb polymetallic sulfide ore from Hanyuan area in Sichuan province. The Cu-Pb bulk concentrate obtained from bulk flotation was taken as the feed ore for Cu-Pb separation, resulting in 87.12% copper recovery to a copper concentrate grading 18.72% Cu,
containing 0.66% Pb and 22.03% S; 85.72% lead recovery to a lead concentrate grading 59.66% Pb, 0.58% Cu and 14.89% S. Meanwhile, a sulfur concentrate grading 48.73% S, 0.05% Cu and 0.22% Pb with corresponding 87.93% S recovery was obtained by flotation of the Cu-Pb bulk flotation tailings. It is concluded that valuable resources in this lean polymetallic ore can be comprehensively recovered with this technique. |
