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.

What is leaching? | National Critical Zone Observatory

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.

Cyanide Leaching | Mining | SGS

Cyanide leaching has been the industry standard for gold processing for more than 100 years. During the cyanide leach process, a cyanide solution, or lixiviant, is percolated through ore contained in vats, columns or heaps. Gold is dissolved by the cyanide and then removed from the heap or columns.
