In the majority of the zinc operations, sphalerite (ZnS) is associated with galena and often sulfides of iron and copper. It is therefore essential to arrange the flowsheet not only for recovery of the valuable minerals, but also to selectively separate them into products acceptable to the smelters for ultimate conversion into metal. The …
