Sulfide Ore Processing 171 Tcb Metals And Refining

Processing sulfide ores historically miners have shipped their sulfide concentrates to overseas smelters that have little to no regulations or emissions controls however with the implementation of the mercury export ban of 2008 and the high costs of installing equipment to prepare sulfide ores for cyanide leaching many companies are searching for alternative forms of processing their sulfide ores

Sulfide Ore An Overview Sciencedirect Topics

Sulphide ores are a major source of cu ni and precious metals a basic principle of the extraction processes is to blow air into the molten sulphide in order to oxidise 1 s which forms a gas and 2 fe which forms predominantly feo and then partitions to a slag phase which covers the matte a key element in the recovery of the metals is the solidification of the matte which separates into a sulphur
