Company
A trading company for tungsten and tantalum
Claus Minerals OÜ was registered in Tallinn in October 2026. We buy concentrate from mines and processors that pass our supplier checks, and sell it to industrial users under clear contract terms.
We keep the range narrow on purpose. Two products let us know each supplier, each grade and each buyer’s requirements in detail.
