(i) In gravity separation method, the ore having high specific gravity is separated from the gangue that has low specific gravity by washing with running water. (ii) Ore is crushed to a finely powered form and treated with rapidly flowing current of water. (iii) During this process the higher gangue particles are washed away by the running water. (iv) This method is generally applied …

Hematite is iron oxide, a weakly magnetic iron mineral with an iron content of up to 70%. Mineral separation is the process of converting raw ore into high-quality products while meeting the market demand for steel …
The specific gravity of iron-bearing minerals is usually higher than the specific gravity of gangue materials. Effectiveness efficiency of the gravity separation depends largely on proper crushing and sizing of the ore so as to ensure a proper size feed to the gravity separation equipment and also removal of slime from the equipment.
The typical processing methods include gravity concentration [13,14], magnetic separation [15, 16], froth flotation [17][18][19], and their combinations such as low-intensity magnetic separation ...
Haematite ore is a combination of Iron and oxide and also it is a heavy mineral oxide. Hence, gravity separation is used. $therefore $ Haematite ore is concentrated by "Gravity separation method". The correct option is (A). Note: Carbonate ores can also be concentrated by gravity separation methods. It is also called hydraulic washing.
Dense medium separation (DMS) and gravity concentration are the beneficiation processes used. Iron ore production in this size range is almost exclusively based on haematite. Table I provides a summary of the processes commonly used for various size fractions. The beneficiation of -200 µm iron ore will become more important as lower grade

Iron oxide has magnetic properties and hence, magnetic separation is the best method which can be used for beneficiation of the hematite. Therefore, the option 2 is correct. The concentration of haematite is done by Gravity separation method. Gravity method is based on the difference among the densities of the ore particle and gangue.
Example 3 Question: The gravity separation process is used for the concentration of: 1) Calamine 2) Haematite 3) Chalcopyrite 4) Bauxite . Solution: Gravity separation is effective for concentrating heavier ores. Haematite is concentrated by gravity separation due to its density. Therefore, the correct answer is option (2) Haematite.

Gravity separation is one of the method used for concentration of ore. This process is based on the difference in the density of the ore and the gangue particles. During this process, finely powdered ore is treated with a stream of water. The lighter gangue particles are washed away leaving behind the heavier ore particles.
