Question

Levigation takes advantage of the difference in the specific __ of the ore and the gangue particles

• A. gravity
• B. volume
• C. weight
• D. mass

Answer 1

The correct option is A gravity

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 setup for the process is enabled to take advantage of the difference in the specific gravity (relative density) of ore and gangue particles.
