| titleOfInvention | Gold leaching agent based on ionic liquid and gold leaching method |
| abstract | The invention discloses a gold leaching agent based on ionic liquid and a gold leaching method. The gold leaching agent based on the ionic liquid is prepared by mixing 1-methyl-3- (4-diacetoxyiodobenzyl) imidazole tetrafluoroborate, the ionic liquid and water according to the mass ratio of 1:1-20:20-140, wherein the ionic liquid is the ionic liquid containing halogen anions or dicyandiamide ions. The invention provides a gold leaching method based on ionic liquid, which comprises the following steps: 1) preparing the gold leaching agent based on the ionic liquid; 2) adding a sample containing noble metals into the gold leaching agent obtained in the step 1), and fully stirring to leach the noble metals. The gold leaching agent disclosed by the invention is green and environment-friendly, has good oxidizability and coordination capacity, can be used for leaching precious metals such as gold, palladium, platinum and rhodium, and is high in gold leaching speed and high in extraction rate. |
