Answer:
An ore of tin-containing FeCrO4 is concentrated by magnetic separation as FeCrO4 is ferromagnetic in nature. Magnetic separation based on differences in magnetic properties of the ore components. Iron ores are attracted towards the magnet, hence, non-magnetic impurities can be separated from them using magnetic separation.
Magnetic separation
Magnetic Separation is one of the most common and important physical separation techniques. Magnetic Separation is which separating components of mixtures by using magnets to attract magnetic materials or magnetically susceptible particles or bodies are separated from non-magnetic particles.
