Question
Gravity separation is generally applicable for heavier ores such as Haematite and Cassiterite.
Answer: Option A
:
A
Gravity separation also known as hydraulic washing is based on the differences in weight between the gangue and the metal. In general, the metal particles of the ore are heavier than the impurities. So we use the principle of gravity separation to separate the two.
Finely pulverized (powdered) ore is treated with a stream of water such that the lighter gangue particles are washed away leaving behind the heavier ore particles. This is particularly applicable for heavier ore like Cassiterite and Haematite.
