Leaching (chemistry)
Leaching is the process of extracting substances from a solid by dissolving them in a liquid, either naturally or through an industrial process. In the chemical processing industry, leaching has a variety of commercial appliions, including separation of metal from ore using acid, and sugar from sugar beets using hot water.

Leaching may also occur high above soil, regolith, and rock, in the tree tops. As rainfall lands upon the leaves, the water interacts with the leaf surface and may accumulate dissolved ions from the leaf. This process of rainfall removing dissolved ions from leaves is commonly referred to as foliar leaching.
