| Abstract: | The paper investigated the leaching and adsorption process,mass fraction of sodium cyanide in CIL leaching cell,mass concentration of carbon in leaching and adsorption cell in Sunit ore-dressing plant,and analyzed problems existing in CIL plant and further led to technical renovation. Shortening leaching time,reducing mass fraction of sodium cyanide in leaching and increasing carbon mass concentration in leaching and adsorption cell and such measures can save power consumption of 80 × 104kW· h and sodium cyanide of 60 t,increase gold recovery by3. 5 kg,offering significant economic benefits. |
