Ion exchange recovery of silver from concentrated base metal-chloride solutions
(Elsevier, 2015)Ion exchange has not been extensively studied nor industrially used for recovering small amounts of silver from concentrated base metal-chloride solutions. A novel multistep process utilizing a weak anion exchanger with ... -
Removal and recovery of arsenic from concentrated sulfuric acid by solvent extraction
(Elsevier, 13.05.2019)Arsenic-contaminated sulfuric acid solutions are produced in large quantities as by-product during pyrometallurgical processing of sulfide minerals. Options for re-using such acid solutions are increased if the arsenic is ... -
Removal of calcium and magnesium from lithium brine concentrate via continuous counter-current solvent extraction
(Elsevier, 2016)In this research project, a process for purifying Li brine concentrate with a typical composition of Li 30 g/L, Ca 1.36 g/L, Mg 0.049 g/L via solvent extraction was studied. The goal was to remove Ca to below 20 mg/L and ...
