What we claim as new and desire to protect by Letters Patent of the United States is: 1. A process for separately recovering zinc and lead values from zinc and lead containing sulphidic ore which also contains iron, the process comprising subjecting ground ore to a first flotation step to float an initial lead concentrate containing zinc and produce zinc and iron containing tailings ...
The differential leadzinc flotation process has been practised since 1912, yet selectivity in the process remains a significant technical issue in many operations. The minerals processing operation at Zinifex Limited's Century Mine, which uses differential flotation, began in November 1999 and the flotation behavior of the ore remains a major ...
In addition in galena flotation it is important to completely remove the zinc in lead concentrates to reduce the waste of this resource and prevent penalty to concentrates (Wills, 2011).For galena, zinc and copper metals usually have been identified as recoverable valuable minerals(Li and Zhang, 2012).
