A Brief Summary of Zinc Oxide Processing Methods Available - Explain the extraction of zinc from its chief ore.
Belgian-type horizontal retorts were operated in Britain as the main zinc-producing process for about 100 years starting in the mid-19th century. The daily output of each retort was about 40 kilograms (90 pounds), and several hundred retorts were banked together and fired by gas.Jun 26, 2021· Jun 26, 2021· The 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 K.
