Cobalt-nickel pertraction refinery to process pregnant leach solution from recycled spent catalysts. Part 1: Cobalt extraction from a binary system
(Taylor & Francis, 2020)Owing to the recent increase in the global demand for Co, new cobalt–nickel refinery capacity is required. While solvent extraction is one of the most important separation and purification techniques in hydrometallurgy, ... -
The cobalt-nickel pertraction refinery to process recycled spent catalysts leach solutions
(North-West University (South Africa), 2019)Over the last two years, the cobalt (Co) price has increased considerably. The observed increase can be attributed to the increase in demand of lithium-ion batteries (LIBs) of which Co forms an integral part. As a consequence ... -
The hafnium-selective extraction from a zirconium(hafnium) heptafluoride ammonium solution using organophosphorus-based extractants
(Taylor & Francis, 2018)The suitability of the organophosphorus-based extractants, DiOPA, Ionquest 801 and D2EHPA was evaluated for the selective extraction of Zr and Hf from an (NH4)3Zr(Hf)F7 acidic solution using both dispersive and pertraction ... -
The separation of light lanthanoids through pertraction
(North-West University (South Africa), 2019)The light lanthanoid elements (57-60) are the most common of the f-block elements. These elements are plentiful and upon their discovery, the specified application of individual elements have grown alongside our ability ...
