Abstract:
1. A method of extracting a metal value comprising: providing a first portion of a first metal-bearing solution to a first circuit of a solution extraction plant comprising a first barren organic stream; providing a second portion of the first metal-bearing solution to a second circuit of the solution extraction plant comprising a second barren organic stream, wherein the first circuit of the solution extraction plant and the second circuit of the solution extraction plant are in fluid communication; providing a second metal-bearing solution to the second circuit of the solution extraction plant; extracting a first circuit raffinate, wherein the first circuit raffinate is a low-grade raffinate produced by contacting the second metal-bearing solution with the first barren organic stream and the second barren organic stream; extracting a first circuit electrolyte; and extracting a second circuit electrolyte.
