Abstract: 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.

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 Cu2+ 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.

Abstract: A process for recovering non-ferrous metals from a solid matrix may include: leaching the solid matrix with an aqueous-based solution, in a presence of oxygen, to obtain an extraction solution including leached metals and solid leaching residue; separating the solid leaching residue from the extraction solution; and subjecting the extraction solution to at least one cementation to recover the leached metals in elemental state. The leaching solution may include chloride ions. The leaching solution may further include ammonium ions. A pH of the leaching solution may be greater than or equal to 6.5 and less than or equal to 8.5. A leaching temperature may be greater than or equal to 100° C. and less than or equal to 160° C. A leaching pressure may be greater than or equal to 150 kPa and less than or equal to 800 kPa.
