PROCEDIMENTO PER RECUPERARE METALLI NON FERROSI DA UNA MATRICE SOLIDA |
摘要 |
<p>The present invention relates to a process for recovering non-ferrous metals from a solid matrix comprising the following phases: (a) leaching the solid matrix with an aqueous-based solution containing chloride ions and ammonium ions and having a pH within the range of 6.5-8.5, in the presence of oxygen, at a temperature ranging from 100 °C to 160 °C and a pressure within the range of 150 kPa - 800 kPa, so as to obtain an extraction solution comprising the leached metals and a solid leaching residue; (b) separating said solid leaching residue from said extraction solution; (c) subjecting said extraction solution to at least one cementation so as to recover the metals in the elemental state.</p> |
