zinc ore extraction process
Explain the extraction of zinc from its chief ore
Zinc The important ores of Zinc are Zinc blende, Z n S Calamine, Z n C O 3 Zincite, Z n O The extraction of zinc blende involves the following steps i Concentration The ore is crushed and then concentrated by froth-floatation process ii Roasting The concentrated ore is then roasted in the presence of excess of air at about 1200K...
