The study explores the electric-arc furnace reduction of tin slag aimed at producing a columbium-tantalum-bearing alloy. The objective was to enhance the recovery rates of columbium and tantalum from waste materials while assessing the feasibility of the process in industrial applications. Methodologically, batch tests were conducted using steelmaking furnaces, evaluating the effects of silicon additions, energy consumption, and other operational parameters on alloy recovery. Results indicated that silicon significantly increased recovery rates, achieving up to 91.9% for columbium and 90.2% for tantalum in continuous tests within a submerged-arc furnace. The alloy formed was a high-melting and heterogeneous mixture, representing 20 to 30% of the tin slag while containing 80 to 90% of its columbium and tantalum content, whereas alumina and other components were discarded as lean slag. The application of the electric-arc furnace reduced electrical energy requirements and facilitated improved operational efficiency, although challenges in alloy removal and the necessity for enhanced ventilation to manage hazardous dust were noted. Health and safety measures were found to not significantly elevate processing costs.
