Method for selective reduction and recovery of selenium |
| abstract |
(57) [Summary] [PROBLEMS] To recover an aqueous solution containing impurities without performing roasting or distillation, and recover high-quality selenium alone safely and at low cost. SOLUTION: An aqueous solution containing selenium in the form of selenite obtained by chlorine leaching of a copper electrolytic anode slime is reduced at a temperature of 50 ° C. or less in the presence of chloride ions, and the grade is 99.9%. The above selenium alone is recovered as red selenium. Red selenium promotes crystallization by hot water treatment at 50 ° C. or higher that does not contain a selenium compound, and further by heat treatment in air. |
