A method of recovering sulfur dioxide and heavy metals from metallurgical flue gas

摘要

Abstract The present discloses a method of recovering sulphur dioxide and heavy metals from smelting flue gas. The method uses an ammonium sulfide solution to simultaneously remove sulfur dioxide and heavy metals from the flue gas after pre-treatment of the metallurgical flue gas and also to recover and reuse the heavy metals and the sulfur products. The method is simple and easy to operate, is highly efficient in the desulfurisation and the method is also low cost and is suitable for use in industry. Figure 1 Figure 1
