Paper Fluo-Solid Roaster in India Design and Operation

Fluo-solid roaster is now in common application for sulphide roasting to recover gas for acid manufacture and calcines from which metal constitutents are extracted. It can also be used for partial oxidation and sulphatation roasting of concentrates and matte to render them suitable for extractive treatment.

Fluid bed operation: gives precise control of temper- ature without any hot spot and feed material to 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 side of the roaster.
