2022, HydrometallurgyCitation Excerpt :As very important strategic resources, nickel and cobalt are increasingly used in super-alloys (Nilesh et al., 2021; Hoffmann et al., 2021), catalysts (Sam et al., 2021; Wu et al., 2021), magnetic materials (Zolotukhina et al., 2020), hydrogen production materials (Gomez Vidales et al., 2018), methane production materials (Gomez Vidalesa et al., 2020a, 2020b), especially in batteries (Shen et al., 2021; Patil et al., 2020) and super capacitors (Gomez Vidalesa et al., 2020a, 2020b) with the rapid development of the industry. There were many of technologies developed to recover nickel and cobalt, such as chemical precipitation, smelting (Ilyasa et al., 2020), ion exchange (Omelchuka and Chagnes, 2018; Strauss et al., 2021) and solvent extraction (Zhai et al., 2011;Xu et al., 2019; Kongolo et al., 2003). The advantages and disadvantages of these methods are summarized in Table S1.
Solvent extraction-based recovery of Co from leach solutions of Cu[sbnd]Co ores using a Mextral 6103H-naphthenic acid- isooctanol system
2021, HydrometallurgyCitation Excerpt :Cobalt is an omnipresent component of electronic devices and batteries, thus playing an important role in our everyday life (Monge and Gil-Alana, 2019; Zhang et al., 2019). As the shift towards a zero‑carbon- emissions society, particularly travel decarbonization, is expected to further increase the demand for highly efficient Co-based batteries and, hence, for Co, methods of recovering Co from resources such as primary/secondary ores, tailings and spent batteries are highly sought after (Virolainen et al., 2017; Zhai et al., 2011; Crundwell et al., 2011). Among these resources, CuCo ores have the highest significance, especially in the Democratic Republic of the Congo (DRC) (Shengo et al., 2019; Cailteux et al., 2005).
Bioleaching of cobalt from magnetite-rich cobaltite-bearing ore
2021, HydrometallurgyCitation Excerpt :Cobalt is mainly a companion product of metal recovery from sulfide ores (Slack et al., 2017; Nkulu et al., 2019; Dehaine et al., 2021). Cobalt mineral resources can be categorized into five groups: (i) Ni-(Cu,Co) sulfides (carrollite: Cu(Co,Ni)2S4), (ii) Cu-(Co) sulfides, (iii) Co-(As) sulfides (cobaltite: (CoAsS), (iv) Ni-(Co) laterites, and (v) secondary resources (mine tailings, metallurgical waste, copper smelting byproducts, and recycling of spent products (Kapusta, 2006; Zhai et al., 2011; Chao and Bergbreiter, 2016; Liu et al., 2018). The main hydrometallurgical processes for the recovery of cobalt from its primary minerals are acid leaching, high-pressure acid leaching, and reduction roasting-ammonia leaching (Kaya and Topkaya, 2011; Ma et al., 2013; Thubakgale et al., 2013; Zhang et al., 2019b).
