| Abstract: |
| In this paper,the author introduced of detailed laboratory test results of a difficult processing lead ore with high grade and high oxidation rate. The test result founds that “spiral chute concentration– tailings lead sulfide flotation —lead oxide flotation” process achieved good separation indexes : gravity separation lead concentrate grade is 47.40%, recovery rate of lead is 79.87%, and in Gravity separation tailings, Lead sulphide flotation concentrate grade is 61.52%, lead recovery rate 4.02%, Lead oxide flotation concentrate grade is 63.98%, lead recovery rate 13.11%. this technological process provides a technical basis for the development of the mine. |
