Leaching Meaning

Many plant nutrients are lost in regions of substantial leaching, leaving quartz and hydroxides of copper, manganese, and aluminium. This residue forms a distinctive soil type, called laterite, or latosol, which may result in bauxite deposits.The leaching and adsorption behaviour of gold oresDiagnostic leaching was used to show that mineralogy was not an important factor in the enhanced gold extraction in the presence of activated carbon for the ores.
