Leaching

leaching the process of dissolving and removing nutrients from soil, or minerals from rock, by the percolation of water Certain bacteria are able to help in the solubilization of metals from their ores; such bacterial leaching is carried out commercially to recover metals such as copper and uranium leaching (lēch'ing).
