Abstract
RACE EARTH OXIDES CAPABLE OF BEING RE-USED AS AN ABRASIVE ARE RECOVERED FROM AN ABRASIVE WASTE LIQUID BY A PROCESS COMPRISING THE STEPS OF (1) MIXING AND HEATING A RARE EARTH ELEMENT-CONTAINING WASTE LIQUID WITH AN ACID, TO DISSOLVE RARE EARTH ELEMENTS CONTAINED IN THE LIQUID; (2) REMOVING INSOLUBLE MATTER FROM THE RARE EARTH ELEMENT SOLUTION; (3) INCORPORATING A SOLUBLE CARBONATE SALT OR A SOLUBLE HYDROGENCARBONATE SALT, OR AN OXALIC ACID IN THE RARE EARTH ELEMENT SOLUTION, TO CONVERT THE RARE EARTH ELEMENTS TO RARE EARTH CARBONATES OR RARE EARTH OXALATES; (4) SEPARATING THE RARE EARTH CARBONATES OR RARE EARTH OXALATES FROM A SLURRY OF THE RARE EARTH CARBONATES OR RARE EARTH OXALATES; (5) BAKING THE SEPARATED RARE EARTH CARBONATE OR RARE EARTH OXALATE TO PRODUCE RARE EARTH OXIDES; AND (6) RECORVERING THE RARE EARTH OXIDES.
