Abstract

본 발명은 스프레이 로스팅 공정에서 첨가된 아연을 가진 HCl 산세척 산의 재생방법에 관한 것이다. 일차로 일정량의 마그네슘 이온을 폐산세척액에 첨가하는 것이 특징이며, 여기서 존재한 아연의 양과 적어도 동일한 마그네슘 이온의 양을 첨가하는 것이 유용하다.The present invention relates to a process for the regeneration of HCl pickling acid with zinc added in a spray roasting process. It is primarily characterized by the addition of a certain amount of magnesium ions to the spent acid wash, where it is useful to add an amount of magnesium ions that is at least equal to the amount of zinc present.
