How to use leach in a sentence. leaching studies using topcoat for additional existing and new AS are available. N.B.: If studies for the same product with and without topcoat are available, use the leaching rates from the study without top coat for Time 2, if the calculated leaching rates from the study with topcoat using the above AF exceed those from the study without topcoat. Introduction of Vat-LeachingVat leaching has been around since Roman times, but had become viable in 1896, when cyanide leaching began in earnest with the Merrill-Crowe Process.In an article in the Engineering and Mining Journal in December 1999, Lou Cope described the first vat leaching at Homes take in 1901, which later improved the process in 1906 by adding a desliming circuit.

Leaching is defined as the process of extracting a mineral within the use of reagents that dissolve or transform the mineral into soluble salts, to achieve this

The gradual loss of zinc from brass (dezincification) is perhaps the most well-known example of this type of corrosion, but aluminum can also be leached from aluminum bronzes (dealuminification) and nickel from 70/30 cupronickel alloys (denickelification). Leaching is the extraction of a solute from an insoluble solid by contact with a liquid solvent.

Once the chemicals have drained down through the soil, they can leave a crust of soluble salts on the surface, which makes it hard for the soil to absorb water. Removing this crust with water is the other type of leaching. Leaching is a physico-chemical process where minerals in rock masses go through dissolution under percolating water and anion/cation exchange reactions to generate metal salts in solute/colloid phase that migrate and accumulate under hydrological forces.

The leaching mechanism might become diffusion-controlled when, during leaching, a porous product layer forms on the surface of the particle to be leached. This can for example happen in the case of leaching of sulfides where a layer of elemental sulfur can be deposited on the sulfide surface. Laboratory Leaching tests of mine wastes are typically performed using procedures that fall into two basic categories: batch and continuous.

Leaching is actually two important actions occurring simultaneously: (1) chemical interactions with surfaces and (2) physical movement of water.
