Leaching has a variety of commercial applications, including separation of metal from ore using acid, and sugar from beets using hot water. Chloride can also be leached from food. In a typical leaching operation, the solid mixture to be separated consists of particles, inert insoluble carrier A and solute B.

In this work, a miniaturized flow-through leaching test is presented for rapid screening of potential chemical extractants to explore the bioaccessibility of lead (Pb)

Leaching also takes place in nature where the rocks are dissolved by water. Post leaching, the rocks areleft with smaller proportion of minerals that they originally contained. The leaching plant comprises a new 45 x 135 meter building located next to the quay in the Rönnskär industrial area. The annual production will total 25 ktonnes of lead sulphate and 25 ktonnes of copper/zinc sulphate. The leaching mechanism might become diffusion-controlled when, during leaching, a porous product layer forms on the surface of the particle to be leached.

Leaching

Compounds on the surface of minerals can be become dissolved. 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. Leaching definition at Dictionary.com, a free online dictionary with pronunciation, synonyms and translation.
