Incorrect statement in electrolysis of Al2O3 by Hall-Heroult process is : — Metallurgy and Isolation of Elements Chemistry Question

💡 Solution & Explanation

Step 1: Identify the properties of the two minerals: Rutile (TiO2) has magnetic properties, whereas chlorapatite is non-magnetic. Step 2: Because of this divergence in magnetic behavior, they can be easily separated by applying a magnetic field. Step 3: Consequently, the magnetic separation method is used, matching option (c).
