METHOD OF EXTRACTING STIBIUM FROM SULPHATE SOLUTIONS |
摘要 |
FIELD: metallurgy. ^ SUBSTANCE: invention relates to method of extracting stibium from sulphate solutions. Proposed method comprises sorption on anionite and desorption of stibium from anionite by desorption solution. Sorption is carried out using Lewatit K 5517 anionite, while desorption is made via feeding desorption solution through stationary anionite layer at the rate of 0.35-0.46 m/h at 45-50C. Desorption solution represents disulphide alkaline solution with molar ratio S/NaOH=0.5 and/or alkaline solution of sodium sulphide with sodium concentration of at least 26 g/l. ^ EFFECT: stibium extraction and increased stibium concentration in solution intended for electrolysis. ^ 3 dwg, 3 tbl |
