Using the developed three-stage electrodialysis process, 99.3% of nickel is separated in stage 1 and 87.3% of cobalt is then separated in stage 2 using electrodialysis coupled with EDTA. About 99% of lithium is sequentially separated from manganese in stage 3 using electrodialysis with a monovalent cation-exchange membrane.

This residue contained 0.28 pct of the copper, and 79 pct of the cobalt and nickel from the original 25.2-kg batch of concentrate. Using a higher grade feed containing 1.2 pct Ni, the recovery of nickel and cobalt was 88 pct at grades of 16.2 and 11.4 pct, respectively. In each case, 99.7 pct of CuFeS2 was dissolved.

1. Introduction. Cobalt (Co) is an example of geologically scarce metals that are key to many technologies (Nansai et al., 2014).One of the fastest-growing applications of Co is Li-ion batteries (LIBs), that account for over 50% of the current Co demand, and is predicted to grow over 300% within the next decade (Fu et al., 2020).Consequently, a …

An alloy of chromium, cobalt, and nickel has just given us the highest fracture toughness ever measured in a material on Earth. It has exceptionally high strength and ductility, leading to what a team of scientists has called "outstanding damage tolerance". Moreover – and counterintuitively – these properties increase as the material …

Here, in stark contrast to reports of other inorganic nanomaterials, we find that nickel-cobalt alloy magnetic nanocrystals (NiCo NCs) actually inhibit activation of NLRP3, NLRC4 and AIM2 inflammasomes.
