Abstract
Continuation-in-part of U.S. Pat. 4,985,069. The metal ore feed is fluorinated and the resulting compound is reduced with an alkaline- earth metal or alkali metal with the associated purification and ingot casting in an induction-heated furnace apparatus. The process is suitable for recovery and purification of Sc, HF, Nb, Ti, Zr, Or Nd. The ores can be fluorinated with hf, alkaline-earth metal fluorides, or alkaline-earth metal fluorosilicates, and the resulting intermediate compounds can be reduced with ca, mg, na, or k. Thus, a model mixture of 567 g k2zrf6 and 162 g ca in a crucible was heated in an induction furnace and then cooled. The resulting products included 70 g zr at 31 pct yield.
