Abstract

The subject of the present invention is a process for the extraction of sulphur and metals, in oxide form, usable in the Waeltz process, from muds containing compounds of sulphur and of said metals, for example from muds of substances chemically similar to goethite and jarosite. In Figure 1 a flow-chart of an embodiment of the process according to the invention is shown.
