| Abstract: |
| In order to process lead sulfide ore in Langcang Yunnan Province, preferential flotation tests has been conducted through analysis of process mineralogical characteristics. The raw ore sample contains 2.46% Pb and0.45% Zn, ,and a simple flowsheet consisting of one operation of rougher, one operation of scavenger and two operations of cleaner has been developed. The lead concentrates with a lead grade of 54.2%, and lead recovery of 83.45% has been obtained. Results of tests show that the preferential flotation flowsheet of lead is able to process the lead sulfide ore. |
