Abstract:Scrap hafnium-bearing alloy was treated by electric melting and precipitation with phosphate. Current efficiency is 90% above under the conditions including current density of 200~300 A/m2, acidity of electrolyte of 1 mol/L H2SO4, and Ni concentration of 80 g/L. Recovery of hafnium is 90% above when electric solution is heated to 80 ℃ with addition of 1 g/L phosphate. Comprehensive recovery of hafnium is 95% above.
