Cobalt (CO), derived from kobold, means "the devil" (its ore is so toxic that it once threatened its own mining), discovered in 1735. For centuries, blue cobalt salts have consistently given porcelain, bricks and enamels a beautiful color. Cobalt alloy can be used to manufacture jet aircraft propeller, its radioisotopes can be used to treat cancer. Cobalt is a hard metal with steel gray and metallic luster. Cobalt (Co) has an atomic number of 27 and is located in the eighth group of the periodic table. The atomic weight is 58.93. Its main physical and chemical parameters are close to iron and nickel . element.

Cobalt is a magnetic hard metal with high melting point and good stability. Its Curie point (the critical temperature point of loss of magnetism) is 1150 ° C, with permanent magnet, melting point of 1495 ° C, boiling point of 2900 ° C, with high temperature resistance. It is an important raw material for the manufacture of heat-resistant alloys, hard alloys, anti-corrosion alloys, magnetic alloys and various cobalt salts. It is widely used in the aerospace, aerospace, electrical, mechanical, chemical and ceramic industries. Therefore, it is an important strategic material.
China's cobalt metal resources are about 1.4 million tons, most of which are associated resources, and there are very few cobalt deposits. China's cobalt ore grades are low, and they are all recovered as mine by-products. Due to low grade and complicated production process, the metal recovery rate is low and the production cost is high. In 1996, China's cobalt metal production (cobalt content) was 229 tons, cobalt-sulfur concentrate production (cobalt content) was 192 tons, and cobalt oxide was 638 tons. In recent years, the annual consumption of cobalt in China is stable at around 1200t. The domestic cobalt production, including cobalt oxide, is converted into cobalt totaling about 600-700t per year. Domestic cobalt production can not meet domestic demand, and about half of it needs to be imported every year.
