On September 30th, the investment of 120 million APT and tungsten ore deep processing project by Hunan Fuhai Industrial Co., Ltd. was officially started in Sanjiangkou Industrial Park, Yucheng County Economic Development Zone. This is another achievement of the county's investment promotion.
Yucheng is rich in mineral resources. It is a well-known “hometown of non-ferrous metalsâ€. It has proven reserves of more than 30 kinds of minerals such as tungsten, iron, molybdenum, antimony, lead, zinc and rare earth. The reserves of tungsten ore are 80,000. Tons are the first choice for the development of deep processing of non-ferrous metals. The county has a good policy environment, and domestic enterprises can enjoy the support of Guofu County, the revolutionary old district and county, the rising county of central China, the key county of western development, the processing trade transfer base county, and the Hunan Provincial Party Committee and the Provincial People's Government. The various support of the test, the policy is extremely favorable.
The APT and intensive processing projects started this time are based on the county's abundant tungsten resources, and are aimed at improving the recycling of resources and the deep processing of tungsten ore. Efficient development, upgrading the level of the tungsten industry in the city, and enhancing competitiveness will have a positive and far-reaching impact. The total investment of the project is 120 million yuan. It mainly produces APT, tungsten fine powder and its deep processing products, and is constructed in three phases. The first phase of investment is 50 million yuan, the second phase is 30 million yuan, and the third phase is 40 million yuan. The first phase of the construction of the annual design capacity of 5,000 tons of APT production line, the annual sales income of 400 million yuan, a tax of more than 10 million yuan.
Encyclopedia interpretation: APT
Ammonium paratungstate, English name: Ammonium paratungstate English abbreviation: APT
Physicochemical properties
Traits: white crystal, there are two kinds of flaky or needle-like. Solubility: slightly soluble in water, solubility in water less than 2% at 20 ° C, insoluble in alcohol. The ammonium paratungstate is heated to 220-280 ° C to lose part of ammonia and crystal water, which can be converted into ammonium metatungstate. When heated to 600 ° C or above, all ammonia and crystal water are lost, and all are converted into yellow tungsten trioxide.
use
It is mainly used to manufacture tungsten metal powder of tungsten trioxide or blue tungsten oxide; the downstream products of metal tungsten powder are tungsten series, such as tungsten strip, tungsten wire and other electric vacuum materials; there are alloy series, such as tungsten carbide and hard alloy. , alloy blades, alloy drills, alloy molds, etc.; other wear-resistant, pressure-resistant, high-temperature mechanical equipment components. Also used in the manufacture of ammonium metatungstate and other tungsten compounds for the petrochemical industry as an additive.
