CRU estimates China’s cobalt metal capacity is close to 20,000 tonnes, up from around 13,000 tonnes last year. Cobalt occurs naturally as only one stable isotope, cobalt-59. The most obvious contenders right now seem to be lithium and cobalt due to the demand for them in electric vehicles. It is one of the three naturally occurring magnetic metals (iron and nickel being the other two) and retains its magnetism at a higher temperature (2012°F, 1100°C) than any other metal. At the same time, it has appealing white color and shine that resembles precious metals like white gold or platinum. Cobalt futures can be found on the London Metal Exchange under the ticker CO. It is a ferromagnetic, weakly reducing metal that is protected from oxidation by a passivating oxide film. Since cobalt currently makes up between 10 and 33 percent of rechargeable cathodes, the automobile industry is going to need a lot more cobalt to power the future of electric vehicles. Another important use for cobalt is in wear-resistant alloys (e.g., Vitallium), which can be found in orthopedic and dental implants, as well as prosthetic hips and knees. A silver-grey metal, cobalt is produced by reductive smelting, a technique used to produce metal from its ore. As early as to 2250 BCE, Persians used cobalt salts to colour glass blue.

Cobalt is a lustrous very hard silvery metal belonging to a group called the "transition metals". Cobalt also has valuable catalytic properties. Shortly after 1900, the American automotive entrepreneur Elwood Haynes developed a new, corrosion-resistant alloy, which he referred to as stellite. Complications from the use of metal implants and prostheses can arise because of biochemical and histological reactions to some of the materials used [7]. For other uses, see Cobalt (disambiguation). The Chinese and Egyptians also used cobalt in sculpture and pottery art. Metals have transformed the world by providing the resources necessary for creating and developing modern materials and enabling technological progress. As a metal it is very mechanically hard and tough, and it has a very high melting point (hence the smelting problems) and also remains magnetic to the highest temperature of all the magnetic elements. Cobalt is not only found in the cathodes of lithium ion batteries, but also in other popular rechargeable batteries like nickel-cadmium and nickel-metal hydride batteries. D ue to its good temperature resistance, corrosion resistance, and magnetic properties, cobalt is widely used in production and our life. That’s why CoCr alloy has become a quite popular material for jewelry, especially wedding bands. 2.3.2 Discovery.
