COLLECTING METHOD OF MOLYBDENUM OXIDE FROM WASTE CATALYST CONTAINING MOLYBDENUM CAPABLE OF COLLECTING HIGH PURITY MOLYBDENUM OXIDE, NICKEL CARBONATE, AND/OR COBALT CARBONATES AT LOW COST

摘要

PURPOSE: A collecting method of molybdenum oxide from waste catalyst containing molybdenum is provided to collecting molybdenum oxide without going through pre-processing and without using desulfurization equipment.;CONSTITUTION: A collecting method of molybdenum oxide from waste catalyst containing molybdenum includes next steps: leaching exudation by mixing waste catalyst containing the molybdenum with acid; inserting extraction solvent into the exudation; separating an organic layer from an aqueous layer; inserting ammonium adipate solution into the organic layer; separating the organic layer from the aqueous layer; inserting acid solution into the aqueous layer in order to precipitate and filter ammonium molybdate; and collecting a molybdenum oxide by calcinating the ammonium molybdate.;COPYRIGHT KIPO 2012
