Solution

The correct options are
A Magnetic separation.
C Froth flotation.

Chemically, iron pyrite is FeS2.
Magnetic separation is applicable when either the ore particles or the impurities are magnetic (attracted by a magnet) in nature.
In case of iron pyrite the ore particles are magnetic in nature hence it can be concentrated using magnetic separation.

Also as the formula FeS2 suggests - does have sulphur atoms. Froth floatation is mainly used for sulphide ores. So, we can definitely use froth flotation process for concentration.
