SGS Canada's Lakefield laboratories undertook an investigation of lithium solvent extraction from a chloride brine. The extract used was a commercially available beta-diketone reagent (Hallochem's Mextral 54-100) mixed with a liquid phosphine oxide (Solvay's Cyanex 923) in an aliphatic diluent. This work was carried out to expand on the successful results reported by workers from CSIRO in Australia using a beta-diketone reagent of similar chemical structure in a similar extractant mixture. The current report expands on some aspects of the data reported in the earlier study. Extraction with a more concentrated reagent mixture enabled higher lithium loading to be attained. The results of preliminary scrubbing and stripping tests are also reported.
