How to Process Copper Ore: Beneficiation Methods and Equipment

The roughing time for processing the ore in the concentrator is about ten minutes, while the ore contains a large amount of carbonaceous gangue and the divalent sulfur ions disappear quickly in the slurry. So the effect of adding sodium sulfide in batches is better than that of adding it once. Add sodium sulfide proportionally.
