| 发明名称 | Indium recovery method | ||
| 摘要 | According to the present invention, there is provided an indium recovery method for recovering indium from an indium-containing product, including a leaching step of allowing indium to leach into an aqueous hydrochloric acid solution by hydrothermal leaching using the aqueous hydrochloric acid solution as a leaching agent from the indium-containing product to obtain a leachate composed of an aqueous hydrochloric acid solution containing indium, and a separating step of adding a microbe for adsorbing In ions to the leachate to separate indium from the leachate. | ||

| 主权项 | 1. An indium recovery method for recovering indium from an indium-containing product, comprising a leaching step of adding an aqueous hydrochloric acid solution having a concentration of 0.05 to 0.5 M to an indium-containing product to allow indium to leach into the aqueous hydrochloric acid solution by hydrothermal leaching using the aqueous hydrochloric acid solution as a leaching agent from the indium-containing product to obtain a leachate composed of an aqueous hydrochloric acid solution containing indium, and a separating step of adding a microbe for adsorbing indium ions to the leachate to separate indium from the leachate. | ||
