Metallic thorium production was attempted by fused salts electrolysis in an argon atmosphere, using the thorium fluoride double salts system. The electrolyte was pure thorium salts obtained from processing Korean monazite sands through alkali decomposition and solvent extraction. The bath content consisted of sodium chloride -potassium chloride and thorium salt eutectic. Relations between current densities, reacting temperature, salts ratio and particle sizes were investigated. Results were obtained as follows: 1) Current densities were 20 to 25 amp/dm. 2) Optimum temperature was about 800 deg C. 3) The ratio of thorium salt to alkali halides in bath was unimportant at 15 to 50%. Decreasing the thorium salt content of bath below 5% results in a discharge of alkali metal ions at the cathode. Under these conditions, metallic thorium 99% over in purity and current efficiencies 70 to 75% were obtained. (auth)
