Abstract

A series of oil products taken from oil refining factories were used as diluents for copper extraction. The influence of diluents on extraction properties has been investigated. The extractants used are Lix984(Henkel) and M5640(Zeneca), and the adaptability of this diluents to these extractants is compared. The checked extraction properties include loading capacity, extraction and strip kinetics, copper/iron selectivity and phase disengagement. The results showed that DSR3 is a suitable diluent for M5640 and Lix984. Further research has been done to reduce the cost of this product by omitting several steps from its production process.
