The answer is correct.

Levigation is separation involving density also called gravity separation or hydraulic washing where as leaching is a chemical process and magnetic separation involves separation by magnetic properties.

@Dhurvil.

It applies only to magnetic substances.

Levigation is a process in which ore is crushed and passed over a sloping surface with grooves. When water is passed through it or will get collected in the groove while gangue will be carried down.

Levigation is the process of grinding an insoluble substance to a fine powder, while wet. The material is introduced into the mill together with water, in which the powdered substance remains suspended, and flows from the mill as a turbid liquid or thin paste, according to the amount of water employed.
