What is the difference between Biomining and bioleaching?

Biomining is commercially applied to heap leach copper sulfide ores and to pre treat gold ores in which the gold is occluded in sulfide minerals. The ore is irrigated with acidic raffinatethe effluent from the solvent extraction facility where the copper is recovered from the solution and formed into cathodes.

What is leaching in food processing?

Leaching is the loss or extraction of certain materials from a carrier into a liquid (usually, but not always a solvent). and may refer to: Leaching (agriculture), the loss of water soluble plant nutrients from the soil; or applying a small amount of excess irrigation to avoid soil salinity.
