发明名称 PROCESS FOR RECYCLING SPENT POT LININGS (SPL) FROM PRIMARY ALUMINIUM PRODUCTION
摘要 The present invention relates to a process for recycling SPL from primary aluminium production, comprising the steps of grinding the separated fractions or cuts, separating materials by means of mechanical treatment, mixing salt slags with SPL, dissolving in water the product obtained in the previous step, carrying out a chemical reaction between water and the materials to be made inert, sedimenting, removing cyanides, filtering to obtain a soluble fraction and another insoluble fraction, washing the insoluble fraction, crystallizing salts of the soluble fraction and aging or conditioning the insoluble fraction. The present invention further relates to the product obtained by means of said process and the use thereof in different fields of the art.
