Tungsten alloy weights have a long history of development. China has entered the heyday of bronze castings between 1700 and 1000 BC, and the process has reached a fairly high level. Europe also began producing counterweights around the eighth century.
Recently, the China Tungsten Industry Association held a symposium of leaders of tungsten enterprises (groups) in Ganzhou. The meeting unanimously agreed that the participating tungsten enterprises (groups) will jointly maintain the supply order of the tungsten raw material market.
Average content of molybdenum in the earth's crust is 0.00011%, and the global reserves of molybdenum resources are about 11 million tons. Molybdenum has the advantages of high strength, high melting point, corrosion resistance, wear resistance and the like, and is widely used in steel, petroleum, chemical, electrical and electronic technology.
The attributes of China's resource-consuming countries are too strong, and the attributes of resource-producing countries are often overlooked. China's vast land and resources, in terms of mineral resources, is the world's largest leader, tin, gallium, antimony, rare earth, tungsten, molybdenum etc.
Research firm Roskilde recently reported that if no new mine projects are launched in the next few years, China's stricter environmental regulations and the depletion of mine supply may result in a lack of tungsten resources.
The GF strategy released "A-share evolution", proposing financial supply-side reforms to reshape China's dominant enterprises. Among them, the "non-ferrous metal industry: opportunities for new materials" pointed out that small metal fields (rare earth, tungsten, molybdenum, tin) are important strategic metals.
The source of molybdenum concentrate is mainly divided into copper sulfide, tungsten and molybdenum and other associated molybdenum ore (MoS2). During the period of 2011-2015, due to the continuous decline of copper prices, some copper-molybdenum mines accelerated the implementation of associated molybdenum metal.
2019 is the 70th anniversary of the founding of the People's Republic of China. It is a crucial year for the fight against pollution and the success of a well-off society.
