ABSTRACT OF THE DISCLOSURE Elemental sulphur is produced a solid compound of sulphur (e.g. sulphidicores of zinc or copper or calcium sulphate) by subjecting the solid compound of sulphur to conversion conditions in a lower bed to liberate, inter alia, at least one sulphur oxide, and causing the sulphur oxides to pass upwardly through an upper bed containing carbonaceous material (e.g. char or coke optionally dispersed on a low density support) at an elevated temperature to reduce the carbonaceous material. The bottom of the upper bed contacts the top of the lower bed, and preferably, both beds are fluidized A single vessel only is required for the performance of the invention.
