| Abstract: | To process a certain lead-silver ore bearing organic carbon from Dali of Yunnan Province, a selective flotation process consisting of Pb-Ag flotation after decarbonization flotation was adopted. The closed-circuit test produced a carbonaceous product with Pb grade of 3.09% at loss ratio of 1.94%, and Ag content of 40.25 g/t at loss ratio of 2.12%, as well as a lead concentrate grading 63.68%Pb at 94.84% recovery, 753.66 g/t Ag at 94.05% recovery. It is shown that valuable elements of Pb and Ag can be reclaimed effectively with this technique. |
