Leaching geochemistry of soil Britannica

Leaching, in geology, loss of soluble substances and colloids from the top layer of soil by percolating precipitation. The materials lost are carried downward (eluviated) and are generally redeposited (illuviated) in a lower layer. This transport results in a porous and open top layer and a dense, compact lower layer.

The dissolution and leaching of minerals Mechanisms

Leaching is a central unit operation in the hydrometallurgical processing of minerals (Crundwell et al., 2011). Often a leaching stage is one of the initial operations in the process, and as a result the efficiency of leaching has a primary effect on the technical and economic success of a hydrometallurgical business.

What is leaching? National Critical Zone Observatory

Leaching is actually two important actions occurring simultaneously (1) chemical interactions with surfaces and (2) physical movement of water. As the water passes through the rock and soil, it interacts with the surfaces of the materials. Compounds on the surface of minerals can be become dissolved.
