Currently, commercial reprocessing plants use the Purex process, involving the solvent extraction of uranium and plutonium with tributyl phosphate.
32.
They're also using more solvent extraction methods, which tends to be cheaper because it avoids the need for smelting.
33.
What makes the plant unique is that it incorporates a solvent extraction circuit to purify the solution before electrowinning.
34.
This is the biggest Zinc solvent extraction circuit in the world, and one of the biggest solvent extraction plants overall.

36.
As with oxide ores, solvent extraction and electrowinning technologies are used to recover the copper from the pregnant leach solution.
37.
These have been grouped into 3 main categories : Solvent extraction, physically assisted extraction, and subcritical or supercritical solvent extraction.

39.
In some cases, such as with oil or grease, a solvent extraction can be used to collect the evidence for analysis.
40.
In the 19th century it became uneconomical to mine salt, and so solvent extraction using water as a solvent was used.
