  • Zinc Smelting Producing And Classification Metalpedia

    zinc smelting is the process of converting zinc concentrates into pure zinc. the most common zinc concentrate processed is zinc sulfide, which is obtained by concentrating sphalerite using the froth flotation method.there are two methods of smelting zinc: the pyrometallurgical process and the hydrometallurgical process (over 90% of hydrometallurgical process is in the zinc deposits on an aluminum cathode and is harvested. the zinc is then melted and cast into ingots. In a typical refinery flowsheet, zinc concentrate is converted to zinc calcine by burning the concentrate in fluid bed roasters. zinc calcine is the soluble zinc form which is the primary feed for the leaching plant.
