Sand casting is a method of obtaining a casting by pouring molten metal into a sand cavity, cooling and solidifying. When the casting is removed from the sand mold, the sand mold is destroyed, so it is also called one-time casting, commonly known as turning sand.
China is still the world's largest molybdenum producer. China's molybdenum output in the second quarter of 2019 was 230,42 tons, a decrease of 1% from the previous month and a 2% increase from the same period last year.
According to the website of the Ministry of Industry and Information Technology, the Ministry of Industry and Information Technology and the Ministry of Natural Resources jointly issued a notice on the release of the total amount of rare earth and tungsten mining, smelting and separation control indicators.
Tungsten is a rare high melting point metal in nature with a melting point of up to 3,410 ° C. It has high density, high hardness, high wear resistance, high electrical conductivity and high temperature strength.
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.
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.
