“…Therefore, although it is not an actinide, as Ga is present in the bittern in its trivalent oxidation state as an oxyanion, it may be the reason for its good sorption on the sorbent. Considering the structure of the sorbent and its reaction for Co sorption proposed by Vaughan et al (2016), 82 the following mechanisms are suggested in reactions (24) and (25) for Co and Ga retention.…”

“…Advantageously, Co exploration and its recovery is topical with many Australian companies targeting this commodity, thus new methods for its metallurgical recovery are being tested. For example, Co can be selectively extracted from Ni into an immiscible liquid organic phase using solvent extraction (SX; e.g., Kasese Cobalt, Uganda) [60,61]. There are advantages (e.g., fast exchange reaction kinetics) and disadvantages (aqueous-organic phase separation stage of SX is relatively slow requiring large settling ponds at high capital cost) of using SX and on a plant-scale, can cause ongoing challenges [60,61].…”

Newer technologies to enhance recovery include ion-and solvent-resin exchange (e.g., solvent impregnated resin, Lewatit ® TP272; [61]). Application of this type of technology should be considered if pH alterations during the Co precipitation test work do not yield an acceptable recovery (i.e., > 60%).…”

At the Old Tailings Dam (OTD), Savage River, Western Tasmania, 38 Mt of pyritic tailings were deposited (1967 to 1982) and have since been generating acid and metalliferous drainage (AMD). Mineral chemistry analysis confirmed high concentrations of refractory cobalt in pyrite (up to 3 wt %). This study sought to determine, through a series of bench scale tests, if Co could be liberated using biohydrometallurgical techniques. Four bulk tailings samples were collected across the OTD, from up to 1.5 m depth, targeting three sulphide-bearing facies. The study was conducted in four stages: (1) bacterial adaption using BIOX® bacteria; (2) biooxidation optimization with pH, temperature and Fe medium parameters tested; (3) flotation test work to produce a sulphide concentrate followed by biooxidation; and (4) Fe and Co precipitation tests. The BIOX® culture adapted to the bulk composite (containing 7 wt % pyrite) in ~10 days, with biooxidation occurring most efficiently at pH 1.5–1.6 and 40 °C whilst the Fe medium concentration was identified as a less-controlling parameter. Flotation produced a 71% pyrite concentrate with total oxidation occurring after 14 days of biooxidation with 99% of Co leached. At pH 3, Co was effectively separated from Fe, however Ni and Cu were also present in the pregnant liquor solution and therefore required refining before production of cobalt hydroxide, the intermediate saleable product. This study shows that adopting a geometallurgical approach to tailings characterisation can identify if mine waste has commodity potential and how best to extract it therefore unlocking the potential for unconventional rehabilitation of AMD affected sites.

“…Adsorption removal of 60 Co has gained wide attention because of high efficiency, low cost and operation convenience compared with other available removal methods, such as chemical precipitation, reverse osmosis, ion exchange, solvent extraction, coagulation and membrane separation [2,3]. Chitosan has been investegated with the application for 60 Co and other radioactive nuclides adsorption, due to its metal ions adsorption capacity and nontoxicity [4].…”

Adsorption of Co(II) on synthesized chitosan-g-poly (acrylic acid) hydrogel was investigated, using batch adsorption technique under different experimental conditions of equilibrium pH, concentration of common competing ions, contact time and temperature. The Langmuir adsorption model fitted the experimental data reasonably well better than Freundlich model. The maximum monolayer adsorption capacity of Co(II) was 73.0 mg/g at 298 K. Kinetics experiments indicated that the adsorption of Co(II) on synthesized chitosan-g-poly (acrylic acid) hydrogel can be simulated by pseudo-first-order model.
