| titleOfInvention | A kind of Strengthen education method of fine fraction trapping gold |
| abstract | The invention discloses a kind of Strengthen education method of fine fraction trapping gold, the method is by cyanide residue, pyrite cinder, gold-bearing material and the gold lixivants such as pyritic sulfur acid sludge or gold-bearing sulfide ore calcining, pH regulator and oxidant and dispersant etc. join and carry out ball milling leaching in water-based solvent, obtain Ultrafine Grinding and leach slurry, gained Ultrafine Grinding leaches slurry and proceeds in autoclave, add gold lixivant, oxidant and water-based solvent, it is passed through air or oxygen-enriched air again, carry out pressure leaching, filter and separate, obtain golden liquid and leached mud, the method technique is simple, easy to operate, the efficient leaching of fine fraction trapping gold material can be realized, your liquid obtained can use existing activated carbon adsorption desorbing electrolytic, the techniques such as zinc powder (silk) reduction reclaim gold, the suitability is strong, there is significant economic benefit. |
