Manufacturing method of Neutralized gypsum for Cement using Sulfuric acid wastewater

SIN YOU GOON

The present invention relates to a method for manufacturing gypsum for cement and, more specifically, to a method for manufacturing neutralized gypsum to be added to cement using sulfuric acid wastewater generated from processes for producing a semiconductor or a phosphate fertilizer or using phosphogypsum.

본 발명은 시멘트용 석고 제조방법에 대한 것으로서, 보다 상세하게는 반도체나 인산비료 제조 공정에서 발생하는 황산폐수 또는 인산석고를 사용하여 시멘트에 첨가할 수 있는 중화석고를 제조할 수 있는 방법에 대한 것이다.
