Patent number: 11932919Abstract: The present disclosure relates to a metal recovery process comprising a solvent extraction process. In an exemplary embodiment, the solution extraction system comprises a plant with a first and second circuit. A high-grade pregnant leach solution (“HGPLS”) is provided to the first and second circuit, and a low-grade pregnant leach solution (“LGPLS”) is provided to the second circuit. The first circuit produces a rich electrolyte, which can be forwarded to a primary metal recovery, and a low-grade raffinate, which can be forwarded to a secondary metal recovery process. The second circuit produces a rich electrolyte, which can also be forwarded to the primary metal recovery process. The first and second circuits are in fluid communication with each other.Type: GrantFiled: December 29, 2022Date of Patent: March 19, 2024Assignee: FREEPORT MINERALS CORPORATIONInventors: Jason M Morgan, Barbara J Savage, David G Meadows, Wayne W Hazen
