Extraction of Zinc: Process, Ores, Diagram - Embibe
2023.1.25 The principal ore of zinc used for its extraction is Zinc blend \(({\rm{ZnS}})\). As Zinc blend is a sulphide ore, the process used for its concentration is the Froth Floatation Method. The concentrated ore is then roasted in excess air at
