METHOD OF BISMUTH TREATMENT

摘要

FIELD: metallurgy.SUBSTANCE: invention relates to metallurgy of rare-earth metals, particularly to fine cleaning of bismuth of radioactive contaminantsPo with the help of hydrochloric acid solutions. In compliance with this method, prior to bismuth electric refining in hydrochloric acid solution, the latter is brought in contact with organic phase containing hexane-1 and activated carbon. Then, obtained bismuth sponge is fused to bubble the melt with inert gas.EFFECT: high-purity bismuth with low content ofPo.1 ex
