METHOD OF EXTRACTING STIBIUM AND ARSENIUM FROM SOLUTION OF GOLD-CONTAINING CONCENTRATE BIOLEACH SOLUTIONS |
摘要 |
FIELD: metallurgy. ^ SUBSTANCE: invention relates to method of extracting stibium and arsenium from solution of gold-containing concentrate bioleach solutions. Proposed method comprises sorption of stibium and arsenium on anionite. Note here that sorption is performed on Lewatit K 5517 anionite, and stibium and arsenium are desorbed there from. Prior to desorption, anionite is subjected to sulphuric-acid washing out of iron deposit. Washing-out comprises rinsing by 1.2-1.3%-sulphuric acid with S:L ratio equal to 1:4 at 45-50C, flow rate of rinsing solution in anionite of 1.0-1.3 m/h, and dissolution of iron (III). Then, remaining iron (III) is washed out by 3%-solution of sodium sulphite at pH=1.5 and S:L=2. ^ EFFECT: higher yield of stibium and arsenium due to selective wags-out of iron for further desorption of them. ^ 3 dwg, 1 tbl |
