Investigation on Leaching of Flue Dust Roasting of Molybdenite

In order to extract rhenium from roasted molybdenite, rhenium and molybdenium ions were optained by dissolving the rare materials, separation and various concentration methods and finaly crystalizations of rhenium salts. Dissolving process was started with rhenium extraction. It can be use acidic, basic or present of antioxide materials for dissolving. In this study dissolving of flue dust Roasting of molybdenite was proceed with nitrid acid, sodium Hypochlorid, Hydrogen peroxide, oxygen, sodium Hydroxide and calcium Hydroxide and best composition of solvent with suitable concentrations, highest dissolving of rhenium, were selected.
