Recovery of rhenium |
摘要 |
In a process for recovering rhenium, a starting material containing tungsten and rhenium is reacted with sodium hydroxide and an oxidizing reactant to form a fused solid. The fused solid is dissolved in water to solubilize the tungsten and rhenium values and then pass through an anion exchange resin to remove the rhenium values and form a solution containing the tungsten values. The resin is stripped to obtain the rhenium values from the resin.
