Question:medium

The ore of which metal is concentrated by leaching?

Show Hint

Associate the concentration method with the type of ore: - \textbf{Sulphide ores} (e.g., ZnS, CuFeS\(_2\), PbS): Froth Flotation. - \textbf{Oxide ores}: Gravity separation (if dense), Magnetic separation (if magnetic, like Fe\(_3\)O\(_4\)), or Leaching (if amphoteric, like Al\(_2\)O\(_3\)). - \textbf{Noble metals} (Ag, Au): Leaching with cyanide (MacArthur-Forrest process).
