These minerals are refined into tantalum (Ta), tin (Sn), tungsten (W) (referred to as the 3 T’s), cobalt (Co) and gold (Au), respectively, and are used in electronics and other products. In the near future, the metals produced by some smelters may be banned, therefore all of our key suppliers are required to map their supply chains for the metals in their components back down to smelter and then to source.
