A common method of copper recovery from oxide ores is dump leaching in which the excavated ore is crushed and dumped on an impervious surface in "lifts" of anything from 10 to 100 ft deep. Sulphuric acid is sprayed onto the levelled off dump via a network of pipes designed to give even distribution.

Abstract. Solvent extraction for copper was first achieved commercially by use of weak ketoxime reagents which exhibited many limitations in terms of strength, selectivity, phase disengagement and in some cases stability. The more recently developed salicylaldoximes are very strong and highly selective, and they possess very rapid kinetics.
