Leaching - an overview | ScienceDirect Topics

Leaching tests are frequently used to assess the potential risk of a waste to release organic and inorganic contaminants into the environment. Several leaching protocols have been developed with each differing in terms of leaching solution used, liquid-to-solid ratio, contact time, number of extractions and other testing parameters.

Tank leaching - Wikipedia

In tank leaching the ground, classified solids are already mixed with water to form a slurry or pulp, and this is pumped into the tanks. Leaching reagents are added to the tanks to achieve the leaching reaction. In a continuous system the slurry will then either overflow from one tank to the next, or be pumped to the next tank.
