| titleOfInvention | Non-toxic gold leaching agent and preparation method thereof |
| abstract | The invention discloses a non-toxic gold leaching agent and a preparation method thereof, wherein the non-toxic gold leaching agent is mainly prepared from 5-50 parts of transition metal compound, 1-10 parts of organic base, 20-100 parts of carbonate and 20-100 parts of amide compound according to parts by mass. The invention has wide and easily obtained raw material sources, simple process and low cost; the addition of the organic base can promote the forward and reverse reaction, improve the generation rate of the medicament and reduce the consumption cost of the medicament; oxygen-enriched air is adopted in the preparation process, so that the oxygen potential of air in the reaction process can be improved, side reactions are inhibited, and the reaction generation rate is improved; the medicine consumption is small, and the gold leaching effect is good. |
