NTIS: PB 192 418 :11 pages
Misch metal was electrowon from a treated bastnasite concentrate in a ref3-lif-baf2 electrolyte at 950 deg. C. The metal was prepared and tapped from a 1,000-ampere cell, and nearly 100-percent utilization of the rare-earth oxide was achieved. Prolonged operation in a smaller cell (40 amperes) indicated that the composition of the misch metal product was reasonably constant, and no significant increase of impurities, with the exception of carbon, was noted.
