Answer:

Leaching is the process of extracting substances from a solid by dissolving them .... Transport Process and Separation Principles.

Answer 2

Leaching is a major chemical process that is used to extract essential as well as non-essential minerals from a particular rock or stone or such solid object.

• The process involves dissolving the solid substances in a chemically prepared liquid medium.
• Not every such liquid medium needs to act as a solvent.

The principle of the Leaching method involves:

• The soluble portions from the solid rock or other object get dissolved in the chemically prepared liquid medium.
• This leaves out insoluble particles at the bottom and they are usually black.
• After settling at the bottom, these black insoluble substances are separated.
• Thereafter, the dissolved portions are extracted using appropriate extraction procedures.

This is the detailed principle involved in the process of leaching.
