Abstract:
A process for recovering non-ferrous metals from a solid matrix may include: (a) leaching the solid matrix with an aqueous-based solution containing chloride ions, ammonium ions, and Cu 2+  ions, having a pH of 6.5-8.5, in a presence of oxygen, at a temperature of 100° C.-160° C. and a pressure of 150 kPa-800 kPa, so as to obtain an extraction solution comprising leached metals and solid leaching residue; (b) separating the solid leaching residue from the extraction solution; and/or (c) subjecting the extraction solution to at least one cementation so as to recover the leached metals in elemental state. The pH may be greater than or equal to 6.5 and less than or equal to 8.5. Temperature may be greater than or equal to 100° C. and less than or equal to 160° C. Pressure may be greater than or equal to 150 kPa and less than or equal to 800 kPa.

Claim (Index 31):
The process of  claim 28 , wherein the at least one cementation is effected in a plurality of steps, obtaining from each of the steps:\n a metallic cement comprising metal or a combination of metals.
