The key of solvent extraction method is to choose the appropriate solvent and extraction method, but in the extraction process, the comminution degree of raw materials, extraction time, extraction temperature and other factors can also affect the extraction efficiency.

Liquid–liquid extraction Wikipedia

Liquid–liquid extraction (LLE), also known as solvent extraction and partitioning, is a method to separate compounds or metal complexes, based on their relative solubilities in two different immiscible liquids, usually water (polar) and an organic solvent (non-polar). There is a net transfer of one or more species from one liquid into another liquid phase, generally from aqueous to organic.

Solvent extraction and electrowinning Wikipedia

Apr 11, 2005 Solvent extraction and electrowinning (SX/EW) is a two-stage hydrometallurgical process that first extracts and upgrades copper ions from low-grade leach solutions into a solvent containing a chemical that selectively reacts with and binds the copper in the solvent. The copper is extracted from the solvent with strong aqueous acid which then deposits pure copper onto cathodes

Solvent extraction is the preferred method for the final separation of oil from oleaginous materials containing less than 30% oil by weight. For oleaginous materials with less than 30% oil by weight, such as soybeans, cottonseed, dry process corn germ and rice bran, the material is mechanically and thermally prepared and then sent to the solvent extraction process for oil separation.

A Breakdown of Liquid-Liquid Extraction and Solid-Phase

The process begins with a solvent and a feed solution which contains the solute for extraction. When choosing a solvent, there are a few factors to consider in order to facilitate the most valuable results. First, one must consider the ease with which the solvent can extract the solute from the feed solution.
