Embodiment 1
[0022] The method that present embodiment reclaims rhenium and bismuth from acid waste liquid comprises the following steps:
[0023] Step 1, using ion exchange resin to carry out ion exchange adsorption treatment on the acid waste liquid, so that rhenium and bismuth in the acid waste liquid are adsorbed on the ion exchange resin; the acid waste liquid is copper smelting flue gas or molybdenum smelting flue gas passed through acid The solution obtained after washing, the concentration of rhenium in the acid waste liquid is 29.7mg / L, the concentration of bismuth is 47.2mg / L, the concentration of hydrogen ions in the acid waste liquid is 3mol / L, the ion exchange resin It is a strong basic anion exchange resin, and what the present embodiment specifically adopts is a macroporous D296 strong basic anion exchange resin;
[0024] Step 2, using a mixed solution of sodium hydroxide and tartaric acid to desorb the ion-exchange resin adsorbed with rhenium and bismuth in step 1, so that ...
Embodiment 2
[0029] The method that present embodiment reclaims rhenium and bismuth from acid waste liquid comprises the following steps:
