In response to the increasing silver content in the cyanide solution containing precious metal at Shandong Jinchuang Gold & Silver Smelting Co., Ltd., which leads to a significant increase in zinc powder usage during the subsequent replacement process and consequently raises costs, precise silver precipitation tests were conducted on high TDS, high silver cyanide solution containing precious metal. By determining the sodium sulfide dosage, dosing method, and the endpoint potential of the solution containing precious metal system, the silver precipitation rate was improved, and an optimal gold‐to‐silver mass ratio suitable for subsequent processes was established. The test results show that when 0.22 mL of saturated sodium sulfide solution is added to the solution containing precious metal and the precipitation endpoint potential is -217 mV, the silver precipitation rate reaches 80.20 %, with a gold‐to‐silver mass ratio greater than 1∶10. At this point, the silver content in the solution containing precious metal is 87 mg/L, and the quality of the silver sludge is optimal. This technology significantly reduces the silver content in the solution containing precious metal, providing the necessary conditions for the subsequent zinc powder replacement process for the recovery of gold and silver.
