Electro-Winning in Basic Medium, for the Recovery of Tin from By-Products Generated by the Harris I Process, at the Karachipampa Metallurgical Company

The main objective of this thesis project is the implementation of an electro-winning processProcess for metallic tin recoveryRecovery in basic medium using the by-productsBy-products from the Harris I processProcess, which come from leadLead refining at the EMK company. To achieve this, several essential stages were carried out: first, the by-productsBy-products and the solution obtained from them were characterized. Then, electrochemical tests were performed using the obtained electrolyte to determine the optimal operating conditions. These tests were carried out in a parallel electrode system, maintaining a basic pH. The results of the laboratory-scale tests were very encouraging, since they achieved an impressive 99.78% recoveryRecovery of tin by electrolytic treatment under specific conditions. In summary, this project demonstrates the feasibility of implementing the electro-winning of metallic tin at EMK, which entails significant advantages such as increased production efficiency, cost reduction, and a contribution to minimizing environmental impactEnvironmental impact by reducing wasteWaste generation. The results obtained in this phase can serve as a basis for future pilot-scale implementations and could have a positive impact on both the company and the environment.
