Wolframite Concentrate

-Introduction of wolframite concentrate:

Tungsten is a rare element which includes tungsten concentrate and calcium tungstate concentrate. The content of the tungsten in the crust is only 0.8% Tungsten is a kind of lithophile element that mainly in the form of tungstate in pegmatite and hydrothermal deposits. There are approximately 15 well-known tungsten ores. Two of them are main series that are scheelite concentrate and wolframite concentrate.

As our wolframite concentrate, it is the most important ore for tungsten refine. The color of the wolframite is brown to black with metallic or semi-metallic luster. Generally, it is produced in granite and quartz ore with tin ore. Wolframite is produced in high-temperature hydrothermal quartz veins. Wolframite has many types of mineralization, such as frit type, quartz vein type, porphyry type, etc. The most famous one is quartz vein type wolframite.

The most advantage of our products is that not only we strive to high quality standard production, but also we provide reasonable and cheap price for our customers. Our products have greatly high cost performance and cheap price compared with international and domestic markets. Low prices and outstanding products are two highlights that we serve for our customers continuously.

-How do we produce wolframite concentrate:

In recent years, the quality of product can not make customers satisfied by original technological process due to the increased quality requirements from users for tungsten concentrate. However, we have already done the research to improve the quality of wolframite concentrate. Our test uses regrinding and separation-gravity process to reduce the content of impurities such as sulfur, arsenic, phosphorus and calcium in wolframite concentrate. It has achieved a significant result. The content of sulfur, arsenic, phosphorus and calcium in wolframite concentrate has reduced from 3.47%,1.13%,0.054% and 4.38% to 0.12%,0.084%,0.035%和0.23% respectively.

-Advantages of wolframite concentrate:

-The wolframite concentrate is mainly used to produce various deep-processed products of tungsten.

-The tungsten special alloy made of the wolframite concentrate is used on manufactures of high-speed cutting tools, gun bores, barrels, rocket engines and nozzles and tank armors, etc.

-The synthetic material tungsten carbide has high hardness, second only to diamond, and can be used as drill bits, turning tools, etc.

-Our customer representative team is 24-7 online and ready for the phone call for your requirements of the wolframite concentrate.

-Reasonable, cheap price and high cost performance for all of our products.

-Uses of wolframite concentrate:

The wolframite concentrate is the most important tungsten ore mineral. It is used to produce various deep-processed products of tungsten and is mainly used to produce various deep-processed products of tungsten. The wolframite concentrate is used to manufacture high-speed cutting tools and barrels. It is also used to make filaments and cathode materials for X-ray generators.
