Zusammenfassung:	Disclosed is a method for removing sintered exhaust gas dust impurities. The method for removing sintered exhaust gas dust impurities according to one aspect of the present invention comprises the steps of: (a) providing sintered exhaust gas dust containing chlorine; (b) dissolving the sintered exhaust gas dust in a solvent to manufacture a dust solution; (c) performing a solid-liquid separation method using a difference in solubility according to temperature to generate a precipitate from the dust-dissolved solution; and (d) obtaining dust having a reduced chlorine content from the precipitate. 소결 배가스 분진 불순물 제거 방법에 대한 발명이 개시된다. 본 발명의 일 측명에 따른 소결 배가스 분진 불순물 제거 방법은, (a)염소를 포함하는 소결 배가스 분진을 제공하는 단계; (b)상기 소결 배가스 분진을 용매에 용해시켜 분진 용해액을 제조하는 단계; (c)온도에 따른 용해도 차를 이용하는 고액분리법을 수행하여, 상기 분진 용해액으로부터 침전물을 생성하는 단계; 및 (d)상기 침전물로부터 염소 함량이 감소한 분진을 획득하는 단계; 를 포함한다.
