Abrégé
(EN)
The present invention relates to a process for the acid digestion of metal-containing compounds by leaching by means of an aqueous leachant, wherein the aqueous leachant i) contains an alkanesulphonic acid and, if appropriate, sulphuric acid and/or surfactant and/or ii) a mixture of an alkanesulphonic acid salt and sulphuric acid and also, if appropriate, surfactant. Furthermore, an aqueous leachant containing one or more alkanesulphonic acids and, if appropriate, sulphuric acid and/or surfactant and also an aqueous leachant containing one or more alkanesulphonic acid salts and sulphuric acid and, if appropriate, surfactant are also provided by the present invention.
