发明名称 Förfarande för metallåtervinning från material som innehåller dessa
摘要 <p>The invention relates to a method by which the valuable metals and any possible precious metals are recovered from a material containing them, such as the mixed matte formed in a smelter. The valuable metals in the material formed in the smelter are leached with an acidic solution containing sulphate and chloride, from which each metal is separated by means of solvent extraction. In leaching,any precious metals contained in the material remain undissolved in the leach residue, from which they are leached with a solution containing hydrochloric acid in oxidizing conditions and separated from the solution by solvent extraction.</p>
