Leaching (chemistry) - Wikipedia

Leaching is the process of extracting substances from a solid by dissolving them in a liquid, naturally.In the chemical processing industry, leaching has a variety of commercial applications, including separation of metal from ore using acid, and sugar from sugar beets using hot water.Leaching also occurs on its own in nature; for example substances leaching from plants due to rain, dew, mist ...

Solvent extraction in hydrometallurgy

Skorpion flowsheets are discussed. Solvent extraction (SX) is a process by which closely related elements or com-pounds in solution are separated based on the differences in partitioning of the species between two immiscible phases. In the SX process the species of interest is typically extracted from an aqueous phase into an organic phase.
