The process consists of treating zinc containing material, in which zinc can be in the form zinc oxide, zinc silicate, zinc ferrite, zinc sulphide together with a carbon containing reductant/fuel, within a rotary kiln at 1000°C to 1500°C.
Gravity andic separation methods were unsuccessful but in 1901 a new metallurgical process, called flotation, was devised at Broken Hill which achieved recoveries of the zinc minerals from ore upwards of 60 . After considerable experimentation, a selective flotation method which worked onmercial scale was perfected in 1912.
Mining and concentrating Zinc ores are recovered by many mining techniques, ranging from open pit mining mainly in the case of oxidized ore bodies, which are located closer to Earths surface to the normal underground methods used for the more deeply located sulfide ores.
