Separation of Aluminum from More Noble E

This research addresses the growing challenge of recycling scrap aluminum, which often becomes contaminated with more noble elements, complicating the production of high-quality recycled metal. The objective was to develop a simpler and more effective electrolysis cell with a side-by-side design that efficiently separates aluminum from these contaminants. The methodology involved constructing and testing a laboratory electrolysis cell where the anode and cathode metals were positioned next to each other. The results demonstrated a remarkable current efficiency exceeding 80 percent, with a specific energy consumption of approximately 7 kWh/kg of aluminum processed. Notably, the copper concentration in the 7xxx alloy was successfully reduced from 2.1 wt percent to under 20 ppm, showcasing the effectiveness of this new refining method. This innovative design not only promises enhanced aluminum reclamation but also presents potential applications beyond aluminum recycling, opening avenues for further research and industrial adaptation.
