There are following extraction process of silver but not : — Metallurgy and Isolation of Elements Chemistry Question

💡 Solution & Explanation

Step 1: Highly electropositive metals with a strong thermodynamic affinity for oxygen tend to occur primarily as oxides in nature. Step 2: Aluminium fits this profile and occurs most abundantly as Bauxite (Al2O3·nH2O), which is a hydrated oxide ore. Step 3: Silver and copper frequently occur as sulfides or in native states, and lead is mainly found as Galena (PbS). Thus, Aluminium is the correct choice (option c).
