Investigation of Copper Extraction from Aqueous Sulfate Solution in a Rotating Disc Contactor

Abstract

The extraction of copper from aqueous sulfate solution with new extractant Cupromex-3302 (active substance is the 5-nonylsalicylaldoxime) using a rotating disc contactor (RDC) was investigated. It was observed from batch experiments that the best results were obtained with the initial aqueous pH and concentration of Cupromex-3302 of 1.9 and 10% (v/v) respectively. In continuous experiments, the first critical rotor speed based on drop breakage probabilities was determined. Then the effects of rotor speed, dispersed and continuous phase flow rates on hydrodynamic parameters such as static hold-up, mean drop sizes and extraction efficiency were studied. The experimental results were compared with the ones obtained by the empirical correlations for prediction of the dispersed phase static hold-up and mean drop sizes in terms of the operating variables and the physical properties. The results of experiments proved the feasibility of operating the solvent extraction of copper from the aqueous solution using rotating disc contactor.

Hydrodynamic features of pulsed solvent extractor for separation of two metals by using the antagonistic effect of solvents

“…The results showed that the operation conditions in the pulsed column with LIX 84-I or Acorga M5640 extractant helped to perform the extraction process with high efficiency ~ 90.5–99.5% 38 , 39 . The utilization of the rotating disc column with the new extractant [Cupromex-3302] for copper separation showed that the process was achieved with maximum extraction efficiency of 87.44% under the operating conditions: 375 rpm, 6.6 L/h, and 8.4 L/h for agitation speed, aqueous flow rate, and solvent organic flow rate, respectively 40 .…”

Ecologically friendly production of copper powder and elimination of cupric ions from aqueous solutions using D-Glucose and ascorbic acid

“…In fact, copper ion (Cu 2+ ) is considered as an oxidant of ores (Kasaie et al 2016). It is also used in Fehling liquor destined to determine blood sugar level [8].…”
