Study of Co Recovery from NdFeB Scrap AITranslate
Abstract AITranslate
RE is recovered by sulphuric acid dissolution from NdFeB scrap. Good Co recovery is obtained by sulfiding precipitation from the sulfuric acid solution with high-Fe ＆ low-Co content resultant with the addition of Fe scales,Na2 S and S. And Co content in the precipitate can reach 8 mass % with the optimum conditions as follows：Fe ： Co=1.5,Na2S ： Co=2,S ： Co=0.5,pH=2,t=70 ℃ and duration 1 hour.
