The Kinetics Liquid-Liquid Extraction Process of Copper from Solutions of Sulphates with Naphtenic Acid
Iozsef Nagy

Abstract:

This paper presents the experimental determination of kinetic basic quantities (reaction order n=1, activation parameters E=19200 kJ/mol and A=2.65 . 10-2 m . s-1) of the copper extraction process of some sulphates aqueous solutions with naphtenic acid (n=9), on the basis of the reaction CuSO4 + 2 [(C5H9) (CH2)9 COOH] = [(C5H9) (CH2)9 COO]2Cu + H2SO4 taking place at the separation interface of the heterogeneous system formed by the aqueous and organic phases. The preparation of experimental data by the integral method lead to the relation, allowing the calculus of copper instantaneous concentrations (Cu) from the aqueous raffined depending on its initial concentration Co of the aqueous phase and the time t in the conditions of the extraction taking place in a performant installation expressed by the productiviy factor f. Keywords: extraction, white spirit, cathion, copper, naphtenic acid, polymerization
