A kind of extraction agent and extraction method for separating gold |
| abstract |
The invention belongs to the technical field of precious metal separation, and relates to an extraction agent and an extraction method for separating gold. The extractant is a gemini-type pyrrolidine ionic liquid, and the extractant of the invention has simple structure, simple synthesis process and good stability. The extractant has a good extraction and separation effect on gold, and can realize the separation between gold and other metals. In the selective extraction experiment, the extraction rate of gold can reach 99%, while other metals have less than 10%. extraction rate. The extraction and separation method provided by the invention is less affected by the concentration of hydrochloric acid in the water phase, and has good gold extraction effect under different acidity. |
