MOLYBDENUM RECOVERY METHOD USING CHELATE ION EXCHANGE RESIN AND A MOLYBDENUM TRIOXIDE MANUFACTURING METHOD USING THE MOLYBDENUM RECOVERED BY THE SAME

摘要

PURPOSE: A molybdenum recovery method and a molybdenum trioxide manufacturing method using the molybdenum recovered by the same are provided to effectively recover molybdenum from molybdenum waste water without expensive calcium chloride.;CONSTITUTION: A molybdenum recovery method includes the following steps of: preparing molybdenum waste water of pH 2.0 or less; inputting acid solution into a reaction bath filled with a chelate ion exchange resin and acidizing the chelate ion exchange resin by inputting a solvent; inputting molybdenum waste water as much as a break-through capacity of the chelate ion exchange resin and re-inputting a solvent; and recovering molybdenum concentrate by separating the molybdenum absorbed in the chelate ion exchange resin by adding NaOH solution into the reaction bath.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Molybdenum waste water; (BB) Solvent; (CC) Acid solution; (DD) NaOH solution; (EE) Chelate ion exchange resin; (FF) Waste water treatment; (GG) Concentrated molybdenum solution
