The wolfram is a metal with unique qualities, that make it a necessary component in lots of industrial applications.
More than 80% of the wolfram all over the world comes from China, so the supply of this mineral in Europe is limited. Furthermore, China’s inner demand has increased rapidly in the recent years, making the country change from exporter to importer.
Recently, the concern about the security of the wolfram concentrate supply to companies and final users in the industry in the West. For this reason, the wolfram has been included in the “Basic Raw Material” list by the European Union.
The increase in wolfram’s consumption has to do with the global GDP, with a growth outlook in his use of the 3% yearly for the next years.
Wolfram’s recycling is an important source of this mineral for the industry, with some areas in the world already with the maximum levels of recycling. However, as there are factors that make recycling difficult, it is considered that is difficult that the recycled wolfram can supply more than the 30% of the necessities of the world industry every year.
The Barruecopardo Mine, managed by Saloro, will produce 15% of the wolfram production outside China, so its operation is really important to supply Occident.
Many of the properties of tungsten are relatively extreme compared to other metals:
Wolfram’s main use is as tunsgten carbide -also known as Vidia-, which is essential in many industrial procedures, as it allows to drill, cut, press and shape all kind of materials at a high speed and temperatura.
Its hardness, heat resistance and high density makes the wolfram a very versatile material, which has different application areas, specially focused on industrial sector.

CHEMICAL, SPECIALISED APPLICATIONS
The Barruecopardo mine produces a high purity scheelite concentrate.
After dedicating time and effort during the metallurgic trials phases, Saloro has achieved a clean and high quality concentrate, with a wolfram trioxide law over 65% and a small content in penalizing elements. This is achieved by an exhaustive extraction, grinding and concentration gravimetric process.
