Antimony recovery from SbCl5 acid solution by hydrolysis ...
The cathodic metal antimony product may attain over 99.5 % purity after washing . In the acid leaching process, antimony is leached from the anode using hydrochloric acid, often in conjunction with ferric chloride. The acid solution can be treated by hydrolysis or electrolysis, or other methods to get antimony compound precipitation [5–9].
The production of "secondary antimony" (i.e. the recovery of antimony from alloys and residues) forms an important means of obtaining the metal. In the United States of America in 1928, between 170,000 and 180,000 tons of old lead accumulators containing 3 per cent, antimony were available.
