From raw material to powder
In St. Martin im Sulmtal, located in the state of Styria in Austria, the raw material from our mine at Mittersill is combined with globally sourced tungsten concentrate.
Our primary raw material consists of the scheelite concentrate from our own mine along with tungsten concentrate sourced from around the world. To preserve natural resources, we have extensive recycling facilities using secondary tungsten raw materials, and thus closing the material circle. In a first processing step tungsten is extracted from the raw materials into a solution, then cleaned and finally precipitated into a pure intermediate product, ammonium paratungstate (APT).
With our state-of-the art technologies we produce high-end tungsten oxide, tungsten metal and tungsten carbide powders for the powder metallurgical industry. These products meet the highest requirements of purity and reproducibility.
