Project at a Glance
- 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.
