PROCESS FOR EXTRACTION OF SULPHUR AND METALS, IN OXIDE FORM, USABLE IN THE WAELTZ PROCESS, FROM MUDS CONTAINING COMPOUNDS OF SULPHUR AND SAID METALS

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-c...

description 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. La présente invention concerne un procédé d'extraction de soufre et de métaux, sous forme d'oxyde, utilisables dans le procédé de Waeltz, à partir de boues contenant des composés de soufre et lesdits métaux, par exemple à partir de boues contenant des substances chimiquement similaires à la goéthite et à la jarosite. La figure 1 est un schéma représentant un mode de réalisation du procédé de l'invention.
