Tungsten Concentrate Prices Showed Downward Adjustment in China

Analysis of latest tungsten market from Chinatungsten Online

The tungsten market was weak in China in the week began on October 21 due to persistent weakness in the demand side and increased supply of tungsten raw materials. Offers in the market was in the chaos. 

Tungsten concentrate prices showed downward adjustment to $13,043.5/t as the resources became increased but purchasers remained cautious. With the influence of uncertain factors, like cost, demand, inventories and economy, ammonium paratungstate (APT) price dropped to $229.3/mtu. Tungsten powder price dropped below $33.4/kg pressed by thin trading of terminal Carbide Rods Double Holes alloy and product markets. Market participants now mainly take a watchful tungsten carbide plates stance.

Tool market in China

Tool market demand around the world will continue to grow. rock drill bits According to reports, the tool market demand around the world is growing. Among them, it's stable growth in Europe, North America, particularly in Eastern Europe; slight recovery in the Asian market, the market has great potential, significant growth market in Latin America, particularly Mexico. (In the past year, concentric drill bits the reason why the tool market demand growth is slow, mainly because of increased tool life, then there is the request for the entire manufacturing process, replacing the many machines and tools as well as an increase in the application of multi-function tool, alternative many simple single-function tool.) Experts have predicted that in the future users will be more emphasis on the production the factory tool of research and development, not only in materials and surface coating technology, but also in the product and Low Air Pressure Drill Bits its production process of the tool . The expert said that the focus on production practices will help the tool manufacturer to increase market competitiveness in the field in which they are familiar.


5 Companies Fined More Than 3.5 Million Yuan, WO3 Desulfurization Catalyst Reduces Acid Rain

Recently, media reports said Development and Reform Commission (NDRC) of Yunnan Province have maken out the illegal administrative penalties of 5 electric powder enterprises for confiscating their illegal incomes, the total illegal incomes of more than 3.50 million. It is reported that the major reason of the five electric powder enterprises to be punished including that generated and outwardly supplied electricity during the outage of desulphurization facilities, related emission concentration index hourly average Yg6 Carbide Tips exceeds the limit but still requires enforcement of environmental price, and so on. In this regard, I express my deep sorrow, as well as have no more agree for the treatment of NDRC, how dare they generated power under the outage of desulphurization facilities? Today, the whole world is doing environmental protection work, and you commit a crime in spite of a law-enforcement campaign, anyone without you not to be punished?

 The pollution of sulfur dioxide has exceed the smoke pollution and become the first atmospheric pollutants, with the world’ industrialization continues to deepen. Flue gas desulfurization (FGD) is currently the world's only desulfurization method of large-scale commercial applications, and also the most effective and main technical means to control acid rain and sulfur dioxide pollution. Desulfurization tower is commonly tungsten carbide sheet used in desulfurization facilities, and the desulfurization catalyst is a core technology used in desulfurization project, the surface of WOdesulfurization catalyst has tension which can reduce the surface tension of limestone slurry and the critical nucleus radius, thereby strengthening the bisulfite oxidation precipitation of gypsum, to achieve the goal of sulfur dioxide emission reduction. Tungsten trioxide (WO3) is an important intermediate product from tungsten concentrates to pure tungsten; the large amounts of WOare used in the production of pure tungsten, tungsten carbide, etc; In addition, as WO3has catalytic property, it can either as the main catalyst (photocatalyst), and also can be used for preparing denitrification, desulfurization catalyst. In the desulfurization cemented carbide tool catalyst, WOas a main active material which uniformly loading on the carrier, serve to reduce the desulfurization reaction activation energy, and also play the roles of anti vulcanization, anti-sintering of carrier, thereby enhance the desulfurization efficiency and achieve the goal of emission reduction.
