1. First, adjust the alkalinity of ore heap or slurry with lime or other alkali, and adjust the pH value to 11-12;
2. When heap leaching or pool leaching, according to the optimum leaching concentration determined by experiments, a certain concentration of gold extractant solution is prepared for spraying or soaking.
3. When stirring leaching, leaching is carried out according to the optimum pulp concentration, leaching agent concentration and leaching time determined by the experiment.
4. During the leaching process, the concentration of gold leaching agent is determined regularly, and when the concentration decreases, the gold leaching agent is added in time.
5. Because of the different composition and acidity and alkalinity of the ore, the optimum concentration of reagent should be obtained according to the actual ore volume and the experiment of the ore sample, and the leaching reagent should be put in proportion. The concentration of gold leaching agent can be determined according to the method provided by our company (free training test method).
