METHOD FOR CONTINUOUS MONITORING OF EXTRACTION PROCESS

Abstract: continuous monitoring of density in extraction and recovery using pressure density sensors is described herein. metal recovery methods and processes using pressure density sensors are also described herein. a method comprises providing an aqueous material containing target ions to a direct extraction unit; extracting target ions from the aqueous material containing target ions using a selective withdrawal medium to yield an extract and a depleted material; using a pressure density sensor to determine a first density of the aqueous material containing target ions; using a pressure density sensor to determine a second density of the depleted material; comparing the first density with the second density; and operating the direct extraction unit based on the comparison.
