System and method for parallel solution extraction of one or more metal values from metal-bearing materials

A process comprising:

• feeding a first metal-hearing solution to a first solution extraction circuit;
• feeding a second metal-bearing solution to the first solution extraction circuit;
• feeding a third metal-bearing solution to a second solution extraction circuit;
• producing a first rich electrolyte solution from the first solution extraction circuit;
• and
• producing a second rich electrolyte solution from the second solution extraction circuit.

A method for extracting metal value comprising:

• preparing a metal-bearing material;
• performing a reactive process on the metal-bearing material to produce a metal-bearing solution;
• performing a solution extraction process comprising feeding a first stream of a first metal-bearing solution to a first circuit of a solution extraction system, feeding a second stream of the first metal-bearing solution to a second circuit of the solution extraction system, feeding a second metal-bearing solution to the first circuit of the solution extraction system, producing a low-grade raffinate by solution extraction of a low grade pregnant leach solution, producing a first rich electrolyte solution with a first circuit stripping unit, and producing a second rich electrolyte solution with a second circuit stripping unit;
• performing a primary metal value recovery process on the first rich electrolyte solution and second rich electrolyte solution;
• and
• performing a secondary metal value recovery process on the low-grade raffinate.
