Abstract

Materials containing alumina and iron, such as slate, are ground and heated with sulphuric acid or nitre cake and leached, the solution being made up to a dilution such that the weight of the solution is of the order of 150 times the weight of the slate or the like. The solution is then heated to 70-80 DEG C., when part of the iron precipitates as ferric hydrate. The remaining solution is treated for the production of alumina, which may be freed from the remaining iron in known manner.
