Answer 1

Answer:

Levigation is the process of grinding an insoluble substance to a fine powder, while wet.

Explanation:

Answer 2

Answer:

The process of levigation is known as Gravity separation.

Explanation:

• The process of levigation involves the grinding of an insoluble substance to a very fine powder, while wet.

• This process of levigation is also known as Gravity separation.

• This is carried out before metallurgical processes, where the separation of ores and gangue is done based on their different specific gravities.

• Ores with higher specific gravity than the impurities such as oxide ores are concentrated by levigation washing.

• During this method, the material is introduced into the mill along with water, in which the powdered substance remains suspended, and flows out from the mill as a turbid liquid or thin paste whose consistency is completely based on the amount of water employed.

• Tin stone, Haematite are few among the oxide ores which are concentrated by this method.

Since the separation of ores and gangue is based on specific gravities, the process of levigation is known as Gravity separation.
