  • Zinc Production, Application, Price Factors Metal Alloy Agiboo

    In order to refine the zinc to a higher grade ore it is processed in a blast furnace fueled by electricity, coke or natural gas. As the furnace reaches temperatures of up to 1204 degrees Celsius (2200 degrees Fahrenheit) the zinc ore is melted. This process also generates carbon dioxide, which will reattach to the zinc as it cools.
