1, Han Rui Cobalt Industry (603799): the leading share of cobalt resources. China is one of the largest producers of cobalt chemicals, and its output ranks among the top in the world. China is the largest supplier of cobalt products, mainly producing cobalt products such as cobalt tetroxide, cobalt hydroxide and cobalt sulfate, and copper products such as electrodeposited copper and crude copper.
2. Luoyang Molybdenum Industry (603993): the leading share of cobalt resources. On August 6th, 20021year, Luoyang Molybdenum Industry announced that it planned to invest 2.5.1billion US dollars (about 6.5438+62 billion RMB) for the construction of TFM copper-cobalt mixed ore project in the Democratic Republic of Congo.
3. Huayou Cobalt Industry (3006 18): the leading share of cobalt resources. Han Rui Cobalt Industry was founded in 1997, which is one of the few enterprises in China with a complete cobalt industrial chain. Its business scope covers a complete industrial process, including ore acquisition, rough processing, smelting and display, as well as the production of cobalt powder and cobalt compounds. By the end of 2020, the company is the third largest producer of cobalt powder in the world and the largest producer in China.
4. Other cobalt resource concept stocks include Soft Holding, China Power Construction, Meg, China MCC, Xidian Pengxin Capital, Liang Hai and so on.
Application of aluminum ore in daily life;
1, battery material. At present, nearly 40% of cobalt consumption is used for rechargeable battery materials, such as lithium cobaltate for lithium-ion batteries and cobalt oxide for nickel-hydrogen batteries. Cobalt is mainly used in lithium batteries. One of the cores of lithium-ion battery is its cathode material, in which LiCoO2 is used. Lithium cobaltate is a solid electrolyte with high energy density, high environmental protection and safety. The advantages of lithium battery are wide voltage range, high energy density and environmental protection (compared with nickel cadmium and nickel manganese). As the main material of lithium batteries, the world demand for lithium cobaltate in 2008 was 32,900 tons (equivalent to 1.97 million tons of metallic cobalt), and the main countries producing lithium batteries were concentrated in Asia, with Japan accounting for 40%(32%), South Korea accounting for 30%(22%) and China accounting for 28%(44%), of which the actual production share was in brackets.
2. Cemented Carbide and super alloys. Tool steel containing a certain amount of cobalt can significantly improve the wear resistance and cutting performance of steel. Cobalt combines with other metal carbide particles in the alloy composition to make the alloy have higher toughness and reduce the sensitivity to impact. This alloy can be welded on the surface of parts, which can improve the service life of parts by 3-7 times. Stellite containing more than 50% cobalt will not lose its original hardness even if it is heated to 1000℃. When the temperature is above 1038℃, the advantages of cobalt-based alloys are revealed, especially suitable for making high-efficiency high-temperature engines and steam turbines, so cobalt-based alloys are widely used in aerospace and modern military fields.
3. Cobalt blue pigment. The glazes of Tang Sancai, blue-and-white porcelain and cloisonne, which the Chinese nation is proud of, all contain cobalt, and only the blue color of cobalt pigment can last forever. Cobalt as a pigment is mainly divided into three types: cobalt blue pigment, cobalt purple pigment and cobalt black pigment.
