Leaching (chemistry) - Wikipedia

Leaching is the process of a solute becoming detached or extracted from its carrier substance by way of a solvent.. Leaching is a naturally occurring process which scientists have adapted for a variety of applications with a variety of methods. Specific extraction methods depend on the soluble characteristics relative to the sorbent material such as concentration, distribution, nature, and size.

Leaching - chemeurope.com

Leaching of sulfides is a more complex process due to the refractory nature of sulfide ores. It often involves the use of pressurized vessels, called autoclaves. A good example of the autoclave leach process can be found in the metallurgy of zinc. It is best described by the following chemical reaction: 2ZnS + O 2 + 2H 2 SO 4 → 2ZnSO 4 + 2H 2 ...

The Problem of Leaching – Pesticide Environmental Stewardship

Leaching is the movement of contaminants, such as water-soluble pesticides or fertilizers, carried by water downward through permeable soils. Generally speaking, most pesticides adsorb to soil particles (especially clay), become immobile, and do not leach. The fate of mobile pesticides, however, can be thought of as a race between the various degradation processes and leaching to groundwater.

Selective Recovery of Lithium from Spent Lithium-Ion ...

Traditional technologies for the recycling of spent lithium-ion batteries (LIBs) mainly focus on reductive leaching, which often leads to total leaching rather than selective leaching of metals. As a result, loss of valuable metal ions, particularly Li+, occurs in subsequent extraction processes, causing low recycling efficiency of valuable metals.
