Tungsten steel watch on the table toward the front of the watch face with an electric drill drill testing watches hardness, tungsten steel watches results showed high hardness, good wear resistance, strength and toughness.

Tungsten rings gold ring zoned wall coating strength test results show that tungsten gold ring hardness, not easy to scratch, do not wear, good gloss, strong metal.

Jiujiang City, Jiangxi Wuning County HUTANG region through the province of Geology and Mineral Exploration and Development Bureau survey after 18 months of a survey of the area proved reserves of 106 million tons of tungsten ore is the world's largest tungsten mine, it is learned that the proven reserves Jiangxi Province has more than one of the existing reserves of tungsten maintain the sum of the potential economic value of over 300 billion yuan in Jiangxi changed "South Tungsten Copper North" .

This pattern of resource survey of investor listed company from Fujian Province Xiamen Tungsten (600549 . SH).As early as in May 2011, Xiamen Tungsten Jiangxi Jiujiang city government to get support, signed the "Carbide project with CMN's second-largest shareholder, Hong Xiamen Tungsten Molybdenum Co., Ltd., as well as Xiushui County, Jiujiang City cooperation agreement ", which Rainbow Xiamen Xiamen Tungsten and 20 billion yuan to be invested for exploration and mine development tungsten resources.

First pump 60 mesh sieve shaker set under the sand formulated taking the weight ratio of solid and liquid slurry of 20% and pumped to the top of our nylon spiral chute processing so that the slurry flowing down naturally video seen, on the inside of the mineral with a large proportion of particles containing gold, iron ore, tungsten and tin of black sand, and other minerals.Outside next to a light particle, the outermost is muddy water, can spiral off the mud, if applied in the coal mine, but also the separation of pyrite, lower ash content of coal gangue, coal washing works well.

The full name of tungsten carbide alloy industry, also known as tungsten steel, tungsten is the world's one of the hardest metal hardness 8-9M (Mohs hardness standard) between second only to diamonds.

Tungsten Platinum: also known as tungsten tungsten white gold rhodium manufacturing process: the build tungsten gold jewelry and platinum powder molding together into the 3000 degree heat furnace in a vacuum environment for platinum jewelry tungsten powder slowly dissolved , and so that the tungsten gold jewelry to achieve whiter brighter visual effects; from white tungsten to create jewelry, the same with tungsten jewelry hardness, gloss and texture, not color does not wear, but the color than tungsten directly create jewelry whiter, closer to silver.

Tungsten,a metal element, atomic number 74, atomic weight 183.85.Steel gray or silvery-white, high hardness, high melting point, room temperature without air attack; mainly used for the manufacture of the filament and high-speed cutting steel, hard mold, also used in optical instruments, chemistry instruments. China is the world's largest tungsten storage power.
 
Tungsten is part of non-ferrous metals, is also an important strategic metal, tungsten ore in ancient times was called "heavy stone." 1781 by the Swedish chemist Carl Wilhelm Scheele discovered scheelite, and extract new elements acid - acid, in 1783 by the Spanish Air Asia Depp found wolframite also extract the acid, the same year, with carbon reduction of tungsten trioxide first got tungsten powder, and named the element. Tungsten content in the crust is 0.001%. Tungsten minerals have been found in 20 species. Tungsten deposit is generally accompanied by granitic magma activity and the formation. After tungsten smelting after the silver-white lustrous metal, high melting point, great hardness. Tungsten is the highest melting points.

Land and Resources has announced the list of the second batch of 33 mines eligibility for National Mine Park, Chenzhou Mining Shizhuyuan Park and Guiyang Baoshan Mine Park list.

Mine Park is a showcase of human remains of the landscape as the main mining, mining development reflects historical connotations, have research value and educational function, available tour to visit, conduct scientific investigation and scientific literacy of specific spatial zone.
 
China has 61 national parks Mine Park qualification. The unit was awarded the qualification requirements shall be carried out by the Ministry of Land and construction in the park during the two years of construction, the building standards be officially named National Mine Park.
