| titleOfInvention | Manufacturing method of cerium carbonate using ceria abrasive material waste |
| abstract | The present invention relates to a method for producing a ceria-based abrasive, comprising the steps of: obtaining a reclaimed ceria-based abrasive from ceria-based abrasive wastes; subjecting the reclaimed ceria-based abrasive to heat treatment in an oxidizing atmosphere to oxidize and roast; , Adding an organic solvent to the sulfuric acid leach solution to separate the organic phase containing water and cerium (Ce) to extract cerium (Ce), and adding an acid to the organic phase containing cerium (Ce) (Cerium) (Ce); and a step of adding the cerium liquid obtained by the back extraction to an aqueous solution of sodium hydroxide to obtain cerium hydroxide; mixing the cerium hydroxide with hydrochloric acid (HCl) CeCl 3) (by adding and reacting the NH 4 HCO 3) cerium carbonate (Ce 2 (CO 3), ammonium bicarbonate to obtain step and said cerium chloride aqueous solution to obtain the aqueous solution of stage 3) Recycling the ceria-based abrasives waste comprising the relates to a process for the preparation of cerium carbonate. According to the present invention, since cerium (Ce) contained in a ceria abrasive waste including a ceria abrasive, a frit glass, and an inorganic coagulant can be recovered and recycled, environmental pollution can be prevented and resources can be saved, A ceria-based abrasive waste can be efficiently refined at a low cost in a short period of time to obtain high purity cerium carbonate. |
