- Solvent extraction
(also known as chemical extraction) is a cleanup method that uses
solvents to extract or remove harmful chemicals from polluted
materials.
- Cleanup using solvent
extraction is generally quicker than methods that treat the soil in
place. It can be done at the site to avoid trucking polluted soil to
cleanup facilities offsite. This saves money on transport and
disposal of the soil.
- Solvent extraction is
a widely used separation process in many parts of the chemical
industry. It also finds application in the production of
pharmaceuticals, environmental engineering, and the minerals
industry.
- Solvent extraction is
often an alternative to distillation. Both are staged processes that
depend upon the distribution of key components between two
essentially immiscible phases.
- The first metal to be
recovered in significant quantities using solvent extraction was
uranium.
- Today around 25% of
the world’s copper is recovered using solvent extraction and solvent
extraction is considered to be the lowest cost production route for
the production of quality cathode.
- Although the quantity
of precious metals currently recovered using circuits that involve
solvent extraction is small the value of these metals is
significant.
- In a perfect world,
the chemical industry would be able to supply low cost, effective
extractants for every important type of metal separation.
- Solvent extraction has
progressed from being a process which solved some of the
environmental problems of other metallurgical routes to being a
target itself for environmental examination.
- The greatest
contribution in achievements of solvent extraction provided
extractants based on hydroxyoximes. As they were synthesized there
were no better copper extractants, and since then all
investigations were performed in order to improve their properties.
- With the recently
developed technologies that are now under investigations in
demonstration plants and ongoing research into improved
technologies, we can safely predict that solvent extraction will
eventually contribute to an increasing fraction of the copper
produced each year not only from oxide but also from sulphide ores.
