Zinc Smelting Producing And Classificationmetalpedia Zinc smelting is the process of converting zinc concentrates ores that contain zinc into pure zinc the most common there are two methods of smelting zinc the pyrometallurgical process and the hydrometallurgical process over 90 of roasting is a process of oxidizing zinc sulfide Copper Lead And Zinc Smelting And Refining Four processing stages are generally used in hydrometallurgic zinc refining calcining leaching purification and electrowinning calcining or roasting is a hightemperature process 700 to 1000 c that converts zinc sulphide concentrate to an impure zinc oxide called calcine Zincdivision Another Century Of Leadership Cezinc The purified solution is filtered again and stored prior to electrolysis during the first process deleterious elements such as cobalt and nickel are removed from the electrolyte the zinc content increases by about 20 gl to 160 gl zn through evaporation and zinc dust addition the residue from the purification circuit is a zncucdconi cake Zncore Advancedzinc Refining Zncore is an integrated metals production and refining company specialized in the sustainable processing of electric arc furnace dust eafd and spent
