PROCEDURE FOR PRODUCTION OF METALLIC ANTIMONY OUT OF ANTIMONY RAW MATERIAL Russian patent published in 2011 - IPC C22B30/02 C25C1/22 C22B3/16

Abstract RU 2409686 C1

FIELD: metallurgy.

SUBSTANCE: procedure consists in production of solution of tri-fluoride out of antimony raw material. Also, valine (C₅H₁₁O₂N) is added to produced solution of tri-fluoride antimony (SbF₃), till there is achieved mole ratio tri-fluoride of antimony: valine as 1:(0.8-1.0). Further, metallic antimony is electro-chemically extracted from the produced solution by the method of internal electrolysis on a steel electrode.

EFFECT: increased output of antimony, upgraded degree of its purity and reduced power expenditures.
