Experimental Study on Sb Removal from Ta-Nb Ore Decomposition Solution by Reduction with Magnesium Powder and Extraction with 2-Octanol AITranslate
Abstract AITranslate
In view of Sb valence,the extraction performance difference of 2-octanol for Sb（Ⅲ）and Sb（Ⅴ）was studied.It is verified that Sb（Ⅴ）extraction is easier with 2-octanol under the same extraction conditions.Based on the above results,Sb in Ta-Nb ore decomposition solution was reduced with a certain amount of magnesium powder,resulting in transformation of high valence state of Sb into low valence state of Sb and Sb separation from Ta and Nb.The experimental results show that to control Sb content within20×10^-6 in the product of niobium pentoxide,reduction conditions should be 10g/L magnesium powder dosage and 5hreaction duration.
