| titleOfInvention | A kind of environment-friendly gold extraction agent and preparation method thereof |
| abstract | The invention discloses an environment-friendly gold extraction agent and a preparation method thereof, belonging to the technical field of gold extraction from gold mines. The gold extraction agent specifically comprises the following raw materials: 30-40 parts of sodium cyanate, 20-35 parts of sodium hydroxide, 15-25 parts of sodium chloride, 15-25 parts of potassium chloride, 20-35 parts of barium chloride, 25-35 parts of ferric chloride, 15-25 parts of sulfamic acid, 10-25 parts of disodium hydrogen phosphate, lemon 15-25 parts of trisodium acid. The method adopts ordinary low-toxic or non-toxic chemical raw materials, and no highly toxic substances are produced in the production and synthesis process, and has a good gold extraction effect for gold ores containing low arsenic and low sulfur, and gold ores containing other harmful elements, and can be completely removed Arsenic and sulfur harmful substances in gold ore. |
