Rhodium Ore Flotation Process

Rhodium recovery into solution decreases as the sinter hydrochlorination time reduces due to the production of poorly sorbed forms of rhodium, such as [RhCl 6] 2−, [RhCl 6−x (H 2 O) x] x−3, [RhCl 6−x (H 2 O) x] x−2, etc. Based on the chlorination process time of 2 hours the sorption recovery figure is 70.3%. An additional two-hour ...
