The difference between lead debismuthization through Croll- Betterton's method and lead Debesmuthization with Electrolytic method in Trepca complex in Mitrovica

Session

Energy Efficiency Engineering

Description

The process of lead debismuthization in the Trepca complex begins immediately after the zinc removal process and is complicated enough to the final product for reason of numerous technological processes.

Such a process was carried out by Croll Betterton's method and developed according to two variants. According to the first variant the amount of lead bismuth decreased up to 0.01% Bi, while according to the second variant the amount of Bi in the lead decreased up to 0.0034% Bi.

Also the benefit of Bi-rich foam should be subjected to the process of melting and draining (sinking) of Bi-rich foam, the removal of bismuths, the chlorination process and finally the refining of crude bismuth.

While the electrolytic method is based on the Pb-Bi alloy electrolysis, or the electrolytic refining of the bismuth lead lies in distinguishing between the electrochemical potentials of the elements present in the material undergoing the electrolysis process.

For this reason, a new refinery has been constructed where the process of obtaining high-quality bismuth will be carried out electrolytically.
