Cobalt extraction refers to the techniques used to extract cobalt from its sulphidic ores (cobaltite) and oxidic ores (nickel laterite) based on final separation of cobalt from copper and nickel and other elements. The chosen processes for cobalt recovery from primary and secondary materials are presented in this review.

The nodules contain many valuable metals like copper, cobalt and nickel. In recent years, the German Federal Institute for Geoscience and Natural Resources developed a process for the processing of manganese nodules based on a combined pyro- and a hydrometallurgical route.

alloy containing copper and cobalt. The alloy was atomized prior to leaching. With the recent increase in demand for cobalt (and the resulting high metal prices), there has been increasing interest in this process route. There is also an alternative hydrometallurgical …

Hydrometallurgical copper recovery can be conveniently considered in two stages: the leaching stage, in which the various forms of copper in the ore are placed into an aqueous solution, and the recovery stage, where dissolved copper is recovered as solid, nearly pure copper …

Further, crystallization was proposed as alternative method to treat the leach liquor aiming to obtain cobalt sulfate (CoSO 4) as a sub-product of the hydrometallurgical route. 2. Experimental2.1. Materials and reagentsSpent Li-ion batteries used in mobile phones of different manufacturers and sizes were collected for this study.

Another possibility for recovery of cobalt from LIB cathode materials is applying solvometallurgy, where the aqueous phase used in hydrometallurgical processes is replaced by organic solvents.28 Solvometallurgical routes produce less aqueous waste and are often more selective than hydrometal-lurgical processes.28–31 Often used green solvents ...

Finally, it is important to note that the presence of lithium ion in the liquor does not provide any interference, since it is a forming-cation of several ATPS and also does not affect the electrodepositing recuperation of cobalt and copper in hydrometallurgical routes (da Silva et al., 2006, Martins et al., 2010, Rodrigues et al., 2009). 2.5.

recovery of copper and nickel. Cobalt is used for making: super alloys (for parts in aircraft engines), corrosion and wear resistant alloy, high speed stock, catalysts in petro- leum industries cemented carbides and diamond tools, magnetic materials etc. [3]. In India cobalt …

The treatment of manganese noodles with a combined and pyrometallurgical process seems to be a promising concept for the recovery of the valuable metals, copper, cobalt and nickel. In the presented paper, a hydrometallurgical concept of the FeNiCuCo alloy has been developed. Fig. 8 shows the complete flowchart for the suggested treatment.

grade copper SX circuit. The raffinate from this circuit is treated for cobalt recovery. The most common cobalt recovery route involves the sequential precipitation of iron, aluminium and manganese using lime at pH 3.5, followed by cobalt precipitation at pH 8.5. Magnesia, despite being far more expensive, is widely used for cobalt ...

The removal and recovery of metals from hydrometallurgical solutions and waste water prior to their release to the environment are ... AND MAMBA, B.B. Biosorption of cobalt and copper from ...

A dissertation in part-fulfilment of the requirements for the degree of Master of Science in Engineering, Faculty of Engineering and the Built Environment, University of Witwatersrand, Johannesburg. 37.

The Chemical of Africa (CHEMAF) is a hydrometallurgical plant operated in Katanga since 2001. It produces copper metal using a process comprising the sulphuric acid leaching of copper-cobalt oxide ...

Another possibility for recovery of cobalt from LIB cathode materials is applying solvometallurgy, where the aqueous phase used in hydrometallurgical processes is replaced by organic solvents. 28 Solvometallurgical routes produce less aqueous waste and are often more selective than hydrometallurgical processes. 28–31 Often used green solvents ...

A plethora of processing routes are possible. Most hydrometallurgical flowsheets recover cobalt from the raffinate of the low-grade copper solvent-extraction circuit, although dedicated cobalt ...

The further recovery of cobalt and copper ions left in solution can be carried out using the same extractant and LIX65N, respectively . 3.2. Hydrometallurgical recovery of metals from products containing batteries. When it comes to recycling …

hydrometallurgical processing route. The ore is leached in sulphuric acid in reducing ... The results showed that a +63-75µm size fraction had the highest grade of copper and cobalt and was thus used for all the experiments undertaken. The results also indicated ... This compares well to about 40-60% recovery reported when leaching in acid.
