Solvent Extraction Returned

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.

What is Solvent Extraction and Why is it Important ...

The simplest solvent extraction examples may be derived from water and organic compounds. For example: Benzene is non polar and is immiscible in water as the polarity of water is very high. So, if we want to separate benzene from a liquid which contains a component that dissolves in water, then we can mix it with water and the separated layer will be benzene.

In addition it does not have the high iron content of returned cementation liquor which may produce an iron “capping-off” effect in the dump being leached. Fig. No. 1 is a typical flowsheet where the leach liquor is pumped from the leaching circuit through polishing filters into the extraction section of the solvent extraction plant.

Soxhlet extractor - Wikipedia

A Soxhlet extractor is a piece of laboratory apparatus invented in 1879 by Franz von Soxhlet. It was originally designed for the extraction of a lipid from a solid material. Typically, Soxhlet extraction is used when the desired compound has a limited solubility in a solvent, and the impurity is insoluble in that solvent. It allows for unmonitored and unmanaged operation while efficiently ...
