industrial copper solvent extraction process

A two level control strategy that stabilizes and optimizes the production of anindustrialcoppersolventextractionprocessis presented. The stabilizing layer consists of a multi-input-multi-output controller or two single-input-single-output controllers with additional four feedforward compensators that regulate the flow rates in thecoppersolventextractionprocess.

Liquid-liquidextraction- Wikipedia

Liquid-liquidextraction(LLE), also known assolventextractionand partitioning, is a method to separate compounds or metal complexes, based on their relative solubilities in two different immiscible liquids, usually water (polar) and an organicsolvent(non-polar). There is a net transfer of one or more species from one liquid into another liquid phase, generally from aqueous to organic.
