Haematite ore is concentrated by

Hence used for concentrating heavy oxide ore. Froth floatation is mainly used for sulphide minerals,so you can eliminate this option. Amalgamation is done using mercury where you combine two or more entities into a new one. Hand picking is done where the impurities can be seen with the naked eye such as separation stones from rice.
