Abstract

Whilst the flowsheet outlined in Scheme 1 is very efficient in terms of the overall materials balance, there is scope to improve the throughput by increasing the transport efficiency in the solvent extraction step. The mass of copper transferred to the water-immiscible solvent in the extraction stage is limited by the 1 : 2 stoichiometry required to generate a neutral, organic soluble, complex from the monoanionic phenolic oxime reagents. We recognized that the ...
