In Turkey, a water extraction process is used, while in Tasmania, a solvent extraction process is used.
2.
The organic stream is recycled through the solvent extraction process while the aqueous streams cycle through leaching and electrowinning processes respectively.
3.
The first successful solvent extraction process for the recovery of pure uranium and plutonium was developed at ORNL in 1949 . The PUREX process is the current method of extraction.
4.
After the dissolution step it is normal to remove the fine insoluble solids, because otherwise they will disturb the solvent extraction process by altering the liquid-liquid interface.
5.
During the solvent extraction process, the cottonseed kernels are subjected to fine grinding by pushing them through an expander and then the solvent is used to extract most of the oil.
6.
The third phase is the term in solvent extraction given to a third layer ( such as foam and / or emulsion ) which forms from the two layers in the solvent extraction process.
7.
Research continued, with DuPont and the Metallurgical Laboratory developing a redox solvent extraction process as an alternative plutonium extraction technique to the bismuth phosphate process, which left unspent uranium in a state from which it could not easily be recovered.
8.
There are also a number of two-stage direct liquefaction processes; however, after the 1980s only the Catalytic Two-stage Liquefaction Process, modified from the H-Coal Process; the Liquid Solvent Extraction Process by British Coal; and the Brown Coal Liquefaction Process of Japan have been developed.
