Abstract: The roasting of sphalerita concentrate is in important step In the extraction technology of zinc,. Boasting is heating to an elevated temperature, without fusion, of ores o.r metallic compounds in contact with oxidizing materials,. In order to produce chemical change or to eliminate a component by volatilization. In Zinc extraction metallurgy, the oxidizing material is oxygen or air and the object is ,partial or complete elimination of the sulphur in the concentrate,. Most of the Zinc extraction plants used circular multiple hearth furnace of Mcdougall type for roasting of Zinc sulphide until in 1929 burning concentrate process of roasting of Zinc concentrate was developed. This method, also known as flash or suspension roasting, has the advantages of doubling the furnace capacity with saving in the cost of fuel and, production of gases rich enough in. sulphur dioxide for. acid manufacture. This process was, first applied commer. Ially at the Urafs chemical plants.
