How can we separate out Pb, Cu, Sb impurities from BiCl3 solution? Ultimate target is to produce salable Bi-compound.

By EW also tell me which is the feed mineral for your chlorination process? I had study and enveloped process for producing Bi. Bolivia was a main producer’s still is a producers from a bismuth mine at the difference from EW copper and other slimes. Also Bi is recovered from the Tin refining process by thermal crystallizer process.

The initial material is plant intermediate slag, which is being leached in HCl solution and resulting in dissolution of Bi, Cu, Sb& Pb. Our aim is to produce salable Bi-compound. Bi as metal may not be preferred by us since quantities are not very huge.

Chlorination roasting should solve part of your problem instead of acid leaching. BiCl3 fumes at low temperature.
