Processing Mineralogy Study on Lead and Zinc Oxide Ore
The processing mineralogy characteristics of an oxidized leadzinc ore from Sichuan were studied systematically using numerous modern instruments Results showed that lead and zinc oxide content in the ore exceeded the minimum industrial grade, and also included a relatively high concentration of silver and iron This ore is composed of many different mineralsThe principal ore of zinc used for its extraction is Zinc blend ( Z n S) 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 1200 K to obtain zinc oxide ( Z n O) It is then reduced to Z n by coke at a temperature of 1673 KExtraction of Zinc: Process, Ores, Diagram Embibe
