Solvent extraction design consideration for the Tati ...

Nickel solvent extraction circuit (Ni SX) Nickel is recovered from Co SX raffinate using solvent extraction. The extractant employed is the carboxylic-acid based Versatic 10 that is dissolved in a high flashpoint hydrocarbon diluent. By control of the extraction pH, the solvent-extraction process is selective for nickel

Copper SX-EW technology - Semantic Scholar

Copper SX-EW technology 005 A further benefit of the scalable nature of VSFTM solvent extraction technology is that it leads to a more compact plant layout and a reduced need for organic first fill inventory, as often only one VSFTM train is required. This leads to significant savings in investment and operating costs. In the VSFTM technology ...
