Hint: To solve we should know about both processes in which minerals are separated from where they are present. As we know some minerals are present in our soil and some are soluble in different types of composition. Generally, more than one mineral is found together and to make it economically available and usable we should separate them. So, it can be used by us.

Complete answer:
The following are the differences between leaching and levigation:

Leaching Levigation
Leaching is the method of separating or extracting a solute from its carrier material using a solvent.Levigation is a mechanism that washes lighter gangue particles in a current of water. Levigation works by comparing the densities of metallic ore and gangue particles.
Leaching refers to the removal of water-soluble plant nutrients from the soil, as well as adding a small amount of extra irrigation to prevent soil salinity.When powdered ore is agitated with water or washed with an upward stream of flowing water, lighter particles such as sand, clay, and other impurities are washed away, leaving heavier ore particles behind.
A method of extracting minerals such as copper and uranium from a deposit by drilling boreholes into it.This method is used for obtaining oxide ore of Iron and Tin.
Bioleaching is the process of extracting particular metals from their ores using bacteria and fungi.Pulverization by intervention is used with hard crystalline powders that do not crush or triturate easily or gummy-type substance.
The degradation of mineral and organic solutes from soil due to percolation (pedology).Depending on the amount of water used, the mill produces a turbid liquid or a thin paste.

- Levigation agent is a liquid, called as levigating agent which is viscous as well as has a low surface tension to improve ease of wetting soil. It also act as a lubricating agent.
- In a nutshell, leaching and levigation are methods of obtaining information. Both terms are full in their fields, but their usages are different in their fields. Leaching is different from navigation in that it does other things.
