METHOD FOR RECOVERING RHENIUM FROM MOLYBDENUM CONCENTRATE

摘要

PROBLEM TO BE SOLVED: To provide a method for recovering rhenium from molybdenum concentrate in which the volatilization ratio of rhenium oxide can be improved in a way having a higher productivity and safety as compared to the conventional method.SOLUTION: Provided is a method for recovering rhenium from molybdenum concentrate including: a pretreatment step for leaching copper and calcium contained in molybdenum concentrate using a chloride ion-containing acidic aqueous solution; an oxidation roasting step for oxidation roasting the molybdenum concentrate processed product obtained in the pretreatment step; and a step for recovering rhenium oxide volatilized in the oxidation roasting step.SELECTED DRAWING: Figure 1
