Extraction of antimony by a copper chloride extractant ...

Antimony extraction is more effective in chloride concentration range of 1.2 to 2.5 M. To reduce this extraction, the chloride concentration in the aqueous solution should be adjusted to below 1.2 M or higher than 2.5 M. To minimize the antimony extraction, the acidity of the aqueous solution should be kept as low as possible.
