Experimental Study on Resin Gold Extraction in a Certain Mineral Processing Plant
A certain beneficiation plant adopted a full mud cyanide resin gold extraction process,and conducted experimental analysis on the influencing factors of the resin used for gold adsorption.The focus was on the effects of temperature and thiocyanate on resin adsorption.The study showed that the thiocyanate present in the process can desorb the gold carrying resin and reduce its grade;Temperature has a significant impact on resin adsorption of gold.The higher the temperature,the lower the grade of the gold loaded resin.When the temperature reaches 30 degrees,the gold loaded resin exhibits both adsorption and desorption phenomena;Targeted measures have been taken in the workshop to address the above issues,such as reducing the temperature of the precious liquid through a cooling tower,treating the electrolytic waste liquid with activated carbon,reducing the content of thiocyanates,reducing the impact on the process,and stabilizing the production indicators on site.
