Direct Production of Pure Molybdenum Metal from Molybdenite Concentration (MoS2) by using a Plasma-Arc Melting Method

Autor: Kouji Mimura, Michio Nanjo

Publikováno v: Shigen-to-Sozai. 108:111-116

The direct thermal decomposition of molybdenite concentration (MoS2=92.3 mass%, SiO2=3.2mass%, Fe=0.65 mass%) in molten state has been carried out under Ar plasma-arc heating to produce the molybdenum metal product. The product was then refined to pu

Recovery of tantalum metal from Ta capacitor scraps with hydrogen plasma melting and refining

Autor: Michio Nanjo, Thoru Takahashi, Kouji Mimura

Publikováno v: Shigen-to-Sozai. 106:187-192

The scrap of used tantalum capacitor is now an important secondary resource of tantalum and the composition of those scraps is simply identical to Ta-Ta205-Mn02 ternary mixture (Ta is above 90%, Mn and oxygen content are a few percent, respectively).
