2. Organosolv - Wikipedia

   en.wikipedia.org/wiki/Organosolv

   The concentration of solvent in water ranges from 40 to 80%. Higher boiling solvents have the advantage of a lower process pressure. This is weighed against the more difficult solvent recovery by distillation. [2] Ethanol has been suggested as the preferred solvent due to cost and easy recovery.

3. Aqueous two-phase system - Wikipedia

   en.wikipedia.org/wiki/Aqueous_two-phase_system

   Aqueous biphasic systems (ABS) or aqueous two-phase systems (ATPS) are clean alternatives for traditional organic-water solvent extraction systems.. ABS are formed when either two polymers, one polymer and one kosmotropic salt, or two salts (one chaotropic salt and the other a kosmotropic salt) are mixed at appropriate concentrations or at a particular temperature.

4. Accelerated solvent extraction - Wikipedia

   en.wikipedia.org/wiki/Accelerated_solvent_extraction

   The extraction cell is filled with the solid sample to be examined and placed in a temperature-controllable oven. After adding the solvent, the cell is heated at constant pressure (adjustable between 0.3 and 20 MPa) up to a maximum temperature of 200°C and kept at constant conditions for a while so that equilibrium can be established.

5. Solid-phase extraction - Wikipedia

   en.wikipedia.org/wiki/Solid-phase_extraction

   SPE is in fact a method of chromatography, in the sense of having a mobile phase, carrying mixtures through a stationary phase, packed inside a column.The chromatographic process is harnessed to create a solid-liquid extractive technique—allowing separation of a mixture of components by taking advantage of large differences between the solid and liquid phase K eq, or equilibrium constant ...

6. Hydrometallurgy - Wikipedia

   en.wikipedia.org/wiki/Hydrometallurgy

   Hydrometallurgy involve the use of aqueous solutions for the recovery of metals from ores, concentrates, and recycled or residual materials. [1] [2] Processing techniques that complement hydrometallurgy are pyrometallurgy, vapour metallurgy, and molten salt electrometallurgy. Hydrometallurgy is typically divided into three general areas: Leaching
