X-ray fluorescence spectrum analyzer EDX9000B ore plus determination of the main content in tungsten ore and chromite
To meet the needs of iron and steel industry analysis, X ray analysis technology has obtained the innovation and development. Iron and steel smelting process not only requires all elements/oxide analysis, also requires a phase analysis in different stages. Ore XRF analyzer has been as a conventional method used in steel industry of chemical analysis.
Chromite is a kind of mineral crystallization, is mainly composed of ferric oxide (11) and chrome oxide compounds (111). Available chemical formula FeCr204 said. It belongs to the family of spinel oxide minerals. Magnesium can replace iron with different quantity, because it with magnesia chromite (MgCr204) form a solid solution. Aluminum alternative may also occur, leading to almandine (FeAl204). Chromite is mainly used for today through the production of ferrochrome (FeCr) (an iron chromium alloy) to produce stainless steel.

Chromite grains found in large mafic igneous rock intrusion, such as South Africa and India, bush Wilder. Chromite is iron black, with metallic luster, dark brown stripes, mohs hardness of 5.5.
Extracted from chromite chromium has many advantages in terms of use and application. Will use of chromium in the process of human health and the environment around the world have a considerable impact
Tungsten and tungsten, it is a kind of chemical element, symbols for W, atomic number is 74. Rare metals tungsten is naturally on earth, almost entirely with other elements to form compounds. In 1781, it was identified as a new element, and in 1783 was first separated into metal. Its important minerals including scheelite and wolframite, which provides another name for the element.
Free element is famous for its robustness, especially it has in addition to carbon (under normal pressure distillation) of all the elements have been found in the highest melting point, melting point of 3422 C (6192. F; 3695 K). It also has the highest boiling point for 5930 C (10710. F; 6200 K). Its density is 19.25 grams per cubic centimeter, comparative with the density of uranium and gold, and it is much more higher than the density of lead (1.7 times). Polycrystalline tungsten is essentially a and hard materials (under standard conditions, not when combined), make it difficult to processing. However, pure tungsten single crystal more malleable, can use a hard steel hacksaw cutting.

With X ray fluorescence spectrometric Cr203 WO3 and chromite in tungsten ore, through the molten glass sample preparation method, using high purity WO3 or Cr203 measuring X-ray fluorescence intensity count a single standard samples, and then with the unknown sample, compared to X ray fluorescence intensity counting income measures “to calculate the WO3 and Cr203 measurements. Method is used for the determination of tungsten in the sands and chromite WO3 and Cr203, the result is consistent with the values specified in the
EDX9000B ore XRF spectrum analyzer spectra are as follows
