METHOD FOR TREATMENT OF PHOSPHORIC GYPSUM USING FLUE GAS DESULFURIZATION DUST

摘要

The present invention relates to a method for treating waste phosphoric gypsum using flue gas desulfurization dust, wherein the method allows a user to crush flue gas desulfurization dust into a size of 25 micrometers or less, to mix the dust with waste phosphoric gypsum, and to sinter the mixture at 600-650 deg. C. The present invention can prevent environmental pollution by removing heavy metals from waste phosphoric gypsum using the flue gas desulfurization dust. More particularly, the present invention can create economic benefits by recycling waste phosphoric gypsum classified as industrial wastes into value-added resources. [Reference numerals] (AA) Weight
