Cobalt is a relatively rare element of the Earth's crust, essential to mammals in the form of cobalamin (vitamin B12). In humans, the dietary intake of cobalt varies between 5 and 50 μg/day, most of it in the inorganic form. Vitamin B12 represents only a small fraction of the oral Co intake.

Hydrometallurgy plays a dominant role in the extraction, enrichment, and separation of rare metals, precious metals, and aluminum, zinc, nickel, and cobalt, with the advantages of high comprehensive recovery rate of valuable metals, environment-friendliness, and easy realization of continuous and automated production process.
In this paper, the thermodynamic model based on previous lithium extraction study [6] is extended to the application of nickel and cobalt extraction process, addressing the modelling gap in the current lithium-ion battery circular economy. The model's potential lies in streamlining the design of processes aimed to co-extracting metals from ...

There are three well-known methods for roasting spodumene. The first is acid roasting, which involves baking the calcined spodumene product with an excess of concentrated sulphuric acid at a temperature of about 250 °C (for conventional heat treatment) or 320 °C (for microwave irradiation for 20 s) [ 19].
The Cobalt Institute's circular economy report provides a vision of a circular cobalt value chain capable of creating shared value for people and the planet. The report focuses on the key three areas in the cobalt value chain where most progress can be achieved to sustainably match supply with demand: cobalt extraction, use, and recycling.
Combining two or three extraction reagents has also been reported, but these co-extraction methods not only complicated the cobalt extraction process, 10,18,28,29 but also reduced phase separation efficiency, thereby increasing stability of cobalt–nickel extract (i.e., reducing stripping rate), which requires the use of acids with high ...
Cobalt solvent extraction A mineral ore contains cobalt and small amounts of nickel. In order to determine the nickel concentration it must be separated from cobalt. Solvent extraction using 0.01 M 8-hydroxyquinoline in CHCI3 is chosen. Which metal should be extracted from the other, and at what pH Consider Figure 9.3 and connected text. With …
The cobalt extraction was selective with respect to nickel and strongly dependent on the chloride concentration in the aqueous solution. The cobalt extraction is given by an anion exchange mechanism through an endothermic process. Cobalt extractions greater than 98% were obtained using the proposed methods. Cobalt stripping from the loaded IL ...
Abstract. Cobalt (Co) is a potentially critical mineral. Most of its extraction is associated with a by-product of other mineral species such as copper, nickel and manganese, where it is a fundamental piece for activities that have increased their development in recent times such as electromobility, industrial and military applications.

Modern Nickel and Cobalt Industry in China. In 2014, the basic reserves of nickel in China were 2,530,000 tons. China is rich in sulfide-based nickel minerals, which are mostly found in the northwest, southwest, and northeast, and their recoverable reserves respectively accounts for 76.8%, 12.1%, and 4.9% of the total reserves of the country.
The mechanism of extraction was detailed. Cobalt separation was done using the ionic liquid tri-hexyltetradecylphosphonium chloride. More than 90% of cobalt can be extracted with very high separation factors. Nickel and lithium separation was carried out by deep eutectic solvents (DESs) based on lidocaine and carboxylic acids. ...
Cobalt is a strategic and critical mineral whose demand is expected to grow rapidly. This study aims to provide a comprehensive summary of cobalt …
Nickel (Ni) and cobalt (Co) are strategic metals that have found applications in a wide range of metallurgical and industrial uses. In this study, the dissolution of a mixed nickel–cobalt hydroxide precipitate using organic acids (citric, oxalic, and malic acid) was investigated. Citric acid was found to be the best leaching agent yielding the following …
Cobalt metallurgy is a metallurgical technology for extracting metal cobalt or its compounds from cobalt-containing resources. In 1735, Swedish chemist G. Brandt …
In this study, oxidizing roasting, segregation roasting, and magnetic separation are used to extract cobalt and iron from refractory Co-bearing sulfur concentrate. The Co-bearing sulfur concentrate containing 0.68% Co, 33.26% Fe, and 36.58% S was obtained from V-Ti magnetite in the Panxi area of China by flotation. …
The hydrometallurgy process uses reagents such as hydrochloric acid (HCl), nitric acid (HNO3), sulfuric acid (H2SO4), phosphoric acid (H3PO4), organic acids, and hydrogen peroxide (H2O2) to extract and separate the cathode metals, usually operating below 100 °C, and can recover lithium in addition to the other transition metals. 1. …
