Extraction of cobalt (Co) and nickel (Ni) by CFI
The study will use continuous-flow extraction of metallurgical solutions of Co/Ni sulphates solution with Cyanex 272 - which have recently been evaluated for Earth mining - to explore if and how the specific boundary conditions given by asteroids can be approached by flow extraction experiment.
Experiments will be done both at lab-scale with a coiled micro-flow inverter using segmented flow, and at pilot-scale with a re-entrance flow reactor.
The experiment will better show better Co-vs-Ni selectivity determined, which the foremost performance criterion is.
