Abstract

본 발명은 강관회사등에서 배출되는 아연재, 아연플럭스를 염산으로 액화시키고, 얻어진 액상물에 함유된 염화암모늄의 양에 대해 1.2∼2.0몰비량의 질산아연을 첨가하여 염화아연과 질산암모늄이 함유된 액상물을 얻고, 이렇게 얻어진 액상물을 240∼300℃에서 열분해시켜 염화아연의 회수방법을 개시한다.The present invention is to liquefy the zinc material and zinc flux discharged from steel pipe companies and the like with hydrochloric acid, and zinc chloride and ammonium nitrate are contained by adding 1.2 to 2.0 molar ratio of zinc nitrate to the amount of ammonium contained in the obtained liquid. The liquid is obtained, and the liquid thus obtained is thermally decomposed at 240 to 300 ° C. to disclose a method for recovering zinc chloride.
