Solvent extraction (SX) of zinc is useful for the recovery of high purity zinc from the leaching solutions of its sulphide minerals, several low‐grade ores, and secondary materials. The technique is fast, environmentally sustainable, and can be tailored to treat aqueous solutions of diverse compositions. It is particularly useful in the cases where the level of contamination is high and the ...

The demonstrated success of the solvent extraction – electrowinning process in the copper industry for oxide and low grade ores has pushed it into a variety of other metal markets. As a result, SX-EW (and its joining with leaching techniques), has become a critical tool in processing complex ores, and ore sources that would otherwise have been considered uneconomic to process.

A process for recovery of zinc values from aqueous ammoniacal solutions employing certain alkylsalicylaldoximes or acetophenoximes as the extractant. The method also provides a means for separation of the zinc and copper values present in the aqueous ammoniacal solution. The zinc and copper values are separately recovered from the organic phase by pH controlled stripping.

Liquid–liquid extraction (LLE), also known as solvent extraction and partitioning, is a method to separate compounds or metal complexes, based on their relative solubilities in two different immiscible liquids, usually water (polar) and an organic solvent (non-polar). There is a net transfer of one or more species from one liquid into another liquid phase, generally from aqueous to organic.
