Quizplus · Accepted Answer

Tin (Sn) can be refined by processes other than electrolysis, such as by using heat and chemicals (e.g., acid or alkaline solutions) to remove impurities. The other metals listed (Na, Mg, Al, Zn) are typically refined through electrolytic processes due to their reactivity and the efficiency of electrolysis in producing high-purity metals.
