What are the listed companies of cobalt metal?

1, Huayou Cobalt Industry (603799): Huayou Cobalt Industry is a high-tech enterprise specializing in the mining, mineral processing and smelting of cobalt and copper nonferrous metals, as well as the deep processing and sales of new cobalt materials. The company mainly produces cobalt products such as cobalt tetroxide, cobalt tetroxide, cobalt carbonate, cobalt hydroxide and cobalt sulfate, and copper products such as electrodeposited copper and crude copper. Cobalt products are mainly used in lithium ion battery cathode materials, aerospace superalloys, cemented carbides, colored glazes, magnetic materials, rubber adhesives, petrochemical catalysts and other fields. The company is one of the largest producers of cobalt chemicals in China, and its output of cobalt chemicals ranks among the top in the world.

2. Jinling Mining (000655): The main raw material of lithium cobaltate battery (used by Tesla) is cobalt. The listed company producing cobalt in the two cities is Jinling Mining (000655), commonly known as Jinling Cobalt in the industry. 20 1 1 The whole year, * * produced 60. 13 tons of cobalt fine powder metal. In the first half of 20 12, * * produced 30. 12 tons of cobalt fine powder metal and sold 22.23 tons.

Cobalt is a silvery white metal. Cobalt does not react with water at room temperature and is stable in humid air. When heated to above 300℃ in air, it is oxidized to generate CoO, and when heated in white, it is burned to generate Co3O4. Used for manufacturing superhard heat-resistant alloys and magnetic alloys, cobalt compounds, catalysts, etc.

There are two methods: wet method and dry method. The dry process is obtained by roasting cobalt-containing ore and coke in a furnace. Wet method is to dissolve the crude cobalt which is smelted and reduce it to solid metal cobalt in electrolytic cell, which greatly improves the purity of cobalt, which can be increased to more than 99.9%. Cobalt is an important raw material additive in magnetic material industry. Can effectively improve the high temperature resistance and aging resistance of magnetic materials in the finished product process. In addition to zirconium, Brazil's nonferrous metals such as ferroniobium, zirconium and titanium also play an indispensable role in the magnetic source metal and the magnetic material industry.
