Detailed explanation-1: -Leaching is a natural process in which water from the rain, snowmelt, or surface or groundwater dissolves substances in contact with the water on the surface of the Earth, and both water and substance are washed away. This process happens in soil when rainwater leaches nutrients from the soil.

Detailed explanation-2: -Mineral leaching is the key unit operation in metallurgical processes and corresponds to the dissolution of metals. The study of leaching is carried out in many areas, such as geology, agriculture and metallurgy.

Detailed explanation-3: -The process of leaching includes the partitioning of contaminants between a solid and liquid phase (e.g., assuming local equilibrium) coupled with the mass transport of aqueous or dissolved constituents.
