Laboratories
Electrochemical Laboratory
The Electrochemical Laboratory carries out work in the field of separation of metals from post-process solutions of the copper and zinc industry, obtained as a result of the processing and recovery of other metals in technological lines.
It specializes mainly in the recovery and electrodeposition of lead from leaching solutions, including those containing mineral acids, carboxylic acids and alkalis.
