Adhia, J D (1969) First fluo-solid Roaster in India-design and Operation. In: Symposium on Non-ferrous Metals Technology : Papers for presentation, 4th - 7th Dec.1968, National Metallurgical Laboratory (CSIR), Jamshedpur.
THE fluo-solid roaster is a modern device which has passed on to the hands of metallurgists from the oil industry where it was used for the first time by Houndry in 1936, for catalytic cracking of petroleum and since then it has been improved and perfected. It is now in common application for sulphide roasting recover gas for acid manufacture and calcines from which metal constituents are extracted. It can also he used for partial oxidation and sulph- atation roasting of concentrates and matte to render them suitable for extractive treatments. Fluid bed operation gives precise control of temperature without any hot spot and feed material to air ratio. These facts are advantageously used in sulphide roasting. The feed is intimately and rapidly mixed with the air or gas introduced from the bottom of the roaster.
