In 1908, Hunan Huachang Company introduced the volatile roasting method from France and began to use this method to refine it. With the rise of the machinery manufacturing industry, the use and demand of sputum has expanded. After the development of tin mines, the shoal mines such as Banxi, Xinshao Longshan and Taoyuan Woxi in Hunan Province have been developed. Subsequently, some provinces such as Yunnan, Guizhou and Guangxi have also successively exploited some antimony ore. In the decades after 1908, China's production of oysters often accounted for more than 50% of the world's total output. The tin ore production accounted for 36.6% of world production from 1912 to 1935, accounting for 60.9% of the country's total.
Uses: The main role of niobium in alloys is to increase hardness, often referred to as hardeners for metals or alloys. Antimony and antimony compounds are first used in wear resistant alloys, printed lead alloys and the arms industry. With the development of science and technology, it has been widely used in the production of various flame retardants, enamel, glass, rubber, paints, pigments, ceramics, plastics, semiconductor components, fireworks, pharmaceuticals and chemical products. 6. Molybdenum: China's Luanchuan County is rich in molybdenum resources. By the end of 1999, China's total molybdenum metal reserves were 8.336 million tons, ranking second in the world. China's annual output of nearly 30,000 tons of metal molybdenum, also ranked second in the world. Molybdenum mines have 222 production areas and are distributed in 28 provinces (autonomous regions and municipalities). It is mainly in Daheishan, Jilin Province; Yangjiazhangzi and Lanjiagou in Liaoning Province; Jinduicheng in Shaanxi Province; and Molybdenum Mine in Luanchuan, Henan Province. The molybdenum ore resources in Henan Province are the most abundant, and the molybdenum reserves account for 30.1% of the total national reserves.
Uses: Pure molybdenum wire is used in high temperature electric furnace and EDM and wire cutting processing; molybdenum sheet is used to manufacture radio equipment and X-ray equipment; molybdenum is resistant to high temperature ablation, mainly used for gun internal rifle, rocket nozzle, bulb tungsten wire bracket Manufacturing.
