Leaching
Leaching:Leaching is the process by which soluble constituents of a solid are extracted into a liquid phase. Leaching is often used to extract metals from ores, where it is referred to as lixiviation, or to extract soluble constituents from soils or other solids.
leaching fraction
Leaching Fraction:The leaching fraction is the proportion of a solid that is leached out by a given solvent. The leaching fraction can be used to predict how much of a given solid will be dissolved in a given solvent over time.
leaching requirement
Leaching Requirement:The leaching requirement is the amount of water that must be applied to leach out soluble constituents from a given soil or other solid. The leaching requirement can be used to predict how much water will be needed to leach out all of the soluble constituents from a given soil or other solid.
