Figure 1.4-1: Diagram of a typical heap leaching process (Fard). Microbial Leaching of Metals: Another novel approach to separating the desired metal components from raw ore which is currently being researched is using microorganisms such as fungi and bacteria in order to convert metal compounds into their water soluble forms (Brandl).

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.
The process of leaching includes the partitioning of contaminants between a solid and liquid phase (e.g., assuming local equilibrium) coupled with the mass transport of aqueous or dissolved constituents.
