The Development Direction of Tungsten Industry in the World - Ⅱ

 

(3) Tungsten carbide

    Tungsten carbide industry occupies an important position in the national economy. The mainly raw material of cemented carbide is tungsten. According to the pertinent data from U.S., about 50% of the tungsten is used for cemented carbide manufacture. Currently more than 50 countries in the world produce carbide and the annual production is about 2.8 million tons. Developed countries in the world are in a leading position of carbide industry, mainly in the following areas:

    1) Precision dedicated tungsten carbide tools. According to the reports, the large-scale production line of sedan needs a large number of special carbide tools. The statistics data abroad shows that if the annual production capacity is 3 million cars, the requirements of special tungsten carbide tool output value should be $ 200 million to $ 300 million. At present, the productions of precision dedicated tool are basically monopolized by large foreign companies.

    2) Tungsten extrusion technology. For example, the advanced technology of plasticizing extrusion with powder is applied abroad, which is capable to produce ultrafine nanocrystalline carbide cutting tools, and complex shaped products. This technology has very significant economic benefits. For example, the output value of imports carbide bar with screw holes is up to RMB4,000.00/ kg, general ф6mm high-performance hard alloy extrusion bar output value is up to RMB1,000.00/ kg, however, general carbide products output value is only RMB200.00/ kg.

    (3) Nanostructures tungsten carbide. Rutger University took the lead of fluidization thermochemical conversion process (SCP) had successfully developed a nano-structured tungsten carbide cobalt composite powder, and quickly reached the scale of production, the powder grains less than 50 nm. Micro drill, tape cutter, scalpel manufactured by nanostructures  tungsten carbide have two times working life than the currently used microcrystalline alloy products, the nanostructures tungsten carbide will become one of the most popular new materials in the 21st century.

The Development Direction of Tungsten Industry in the World - Ⅰ

 

From an international point of view, the applications of tungsten in national economy are mainly as follows:

   (1) Tungsten processing materials

    Tungsten processing materials include wires, rods, plates and so on. The international development directions of tungsten processing materials are high technical content, particularly high specifications and specific shapes. Such as reliable anti-seismic and sag resistance tungsten wire, tungsten filaments used for special light bulbs, tungsten alloy wire used for electric image tubes, ultra-high precision tungsten narrowbands, high purity and ultra-high purity tungsten used for VLSI Sub microspheres. Currently, the largest tungsten products abroad amounted to 1.2 tons, while China is only 0.2 tons.

   (2) tungsten-based heavy alloy

    Tungsten-based heavy alloy is a class of tungsten – based group (85 to 99% amount of tungsten-containing), which adds Ni, Cu, Fe, Co, Mo, Cr and other elements in the alloy, known as tungsten heavy alloy or high-density tungsten alloy. Tungsten-based heavy alloy is widely used in the military industry and civilian industry, such as penetrators and cluster bombs in military industry, the anti-X-ray and G-ray shielding materials in medical industry, high-density tungsten alloy vibrator and electrode materials in civilian industry, etc. Tungsten-based heavy alloy consumption in developed countries accounts for about 10% of the total tungsten consumption, the United States is the world's largest producer and consumer of tungsten based heavy alloy, its production has reached more than 1,000 tons per year.

Ice Fishing - Tungsten Style Ice Jigs Work Best in Deeper Water

The recent arctic blast of cold weather has increased ice thickness on the small, shallow lakes and bays. These areas have up to 10 inches of solid ice. When fishing the large, deep lakes, caution must be used. Bring along safety equipment including: spud bar, ice picks, throw cushion with rope and a life jacket. There are still open water areas on these lakes with the windy conditions.

Bluegill fishing was hit and miss on the area lakes. Weeds in 6 to 12 feet of water will hold bluegills, along with deep water 20 to 35 feet. Anglers have reported finding them tight to the bottom. Light 1-pound or 2-pound test line, small No. 14 to No. 16 sized ice jigs, and a spring bobber are a must to finesse bluegills to bite. Wigglers have been the best bait to use for finicky fish. Wax worms, red and white spikes, mousies and ice plastics have also produced. Tungsten style ice jigs will work best in deeper water, while Ratfinkees, Marmooskas, Moon jigs, and tear drops took fish in shallower water with the slower drop.

Ormonde Mining Reveals Drill Results from Spanish Joint Venture

Ormonde Mining this morning unveiled some encouraging drilling results from its Peralonso gold permit in the Salamanca Province of western Spain.

This is part of its joint venture with Aurum Mining.

The best results from the eight holes included 9.2 metres at 2.09 grams per tonne of the precious metal from a depth of 99.8 metres, 6 metres 1.87 grams and 2 metres at 10.18 grams.

The company’s flagship asset is Barruecopardo, a world-class tungsten project in Spain, which is slated to come into production later this year.

Initially producing 12% of non-Chinese world concentrate supply, operations to be expanded to become a major long-life mine.

Hazelwood Gears up for First Production from ATC Ferrotungsten Project

PERTH - tungsten miner Hazelwood Resources on Wednesday reported that first saleable product from its ATC ferrotungsten project, in Vietnam, was expected during the March quarter of this year.

Around 75% of the requisite feedstock for furnace start-up had now been ordered, and final negotiations for the balance of the feedstock was in progress, with the material expected to arrive on-site during February and March.

Stage 1 of the ATC plant has a nameplate capacity of 4 000 t/y of ferrotungsten alloy, equivalent to 3 000 t/y of contained tungsten. A second stage, if completed, would have sufficient capacity to supply around 25% of the world’s ferrotungsten.

The ATC ferrotungsten project is the largest-capacity plant outside of China.

Hazelwood said on Wednesday that the site laboratory was currently being commissioned and newly recruited personnel were receiving training. Production workforce recruitment was continuing.

Meanwhile, drilling had resumed at Hazelwood’s Cookes Creek project, in East Pilbara, targeting electromagnetic conductors that were considered prospective for nickel sulphide and base metals.

Drilling results from a campaign conducted near the Anomaly Hill nickel sulphide discovery were expected shortly.
