| Abstract: |
| A new metal extraction and separation process of zinc/silver/copper from complex zinc concentrates has been developed in which zinc is extracted through roast and sulphuric acid leaching while the residue is treated by cyanidation to leach silver.With low reagent consumption,the process is easily carried corresponding to leaching rates of 95.01% Zn,94.13%Cu and 89.10% Ag,respectively. |
