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 23):
The process of  claim 15 , wherein the at least one cementation is a multiphase cementation which comprises:\n dividing the extraction solution to be subjected to the at least one cementation into at least a first aliquot and a second aliquot; effecting a first cementation phase by adding an excess of precipitating metal to the first aliquot, so as to precipitate a first metallic cement; separating the first metallic cement containing the precipitating metal in excess from a first supernatant solution, and subjecting the first supernatant solution to further cementation; effecting a second cementation phase by joining the first metallic cement to the second aliquot, so as to precipitate a second metallic cement; and separating the first and second metallic cements from a second supernatant solution, and subjecting the second supernatant solution to cementation in the first cementation phase.
