BASE METAL MINERAL FLOTATION PROCESSES |
摘要 |
A process for recovering a secondary base metal mineral from a material containing it involving treatment of a pulp of the material with surface modifying reagent such as a water soluble sulphide. The pulp is subjected to deaeration by introduction of a non-oxidising gas to prevent oxidation of the reagent. The process is applicable to recovery of secondary minerals such as azurite, malachite, cerussite, anglesite and zinc ferrites from host materials.
