Research on the Upgrading G. Bonnivard Bu reau de Recherches Geologiques et Minieres, of Chrome-Bearing Laterites by Alkaline Roasting

A complete laboratory process for the treatment of lateritic ores containing a high proportion of iron, as well as chrome and alumina, has been established. The ores treated originate from the tropical zones and result from superficial climatic alteration. According to recent estimates, the known reserves of such ores reach many billions of tons, thus representing huge potential reserves for the elements they contain.
