| titleOfInvention | Method for enriching and recovering solid gold from gold-containing solution |
| abstract | The invention belongs to the field of metal recovery, and particularly relates to a method for enriching and recovering solid gold from a gold-containing solution. Which comprises the following steps: (1) adding an enrichment material into the gold-containing solution, stirring for reaction, and then carrying out centrifugal treatment, wherein the enrichment material is a polythioamide compound. (2) And (3) taking the precipitate after the centrifugal treatment in the step (2), and heating at 900-1000 ℃ to obtain the solid gold. The enrichment material is cheap and easy to obtain, and can be produced in large quantities. The enrichment method is simple to operate, the method for obtaining the solid gold is simple, convenient, economical and practical, and the gold in the electronic waste can be efficiently recovered, so that the method has great significance. |
