Question

Gravity separation is generally applicable for heavier ores such as $F{e}_2{O}_3$ and $Sn{O}_2$.

• A. True
• B. False

Answer 1

The correct option is A

True

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

The schematic setup is enabled to take advantage of the difference in the specific gravity of ore and gangue particles.
