Abstract
The process of purification of metal-bearing solutions using solvent extraction has proven to be one of the major improvements to the optimization of the metallurgical flowsheet. Numerous improvements have been made throughout the solvent extraction circuit, as well as considerable research on the subject throughout the world which could, if implemented, add considerably to the overall understanding and viability of the process. The paper will discuss the various interactions within the process that could ultimately prove to be the flowsheets of the future.
