| description | The invention relates to a method for efficiently extracting gold, silver and copper from high-silver-copper-calcium complex gold-loaded carbon. The method comprises the following steps that desorption electrolysis raw material gold-loaded carbon is obtained; cyanide-containing backwater is used for flushing and overflowing to remove wood dust impurities in the carbon; cleaning by using cyanogen-containing backwater, blowing air and transferring into a desorption column after mud is cleaned; a gold-loaded carbon desorption electrolyte is prepared, the concentration of sodium cyanide is 0.2-0.3%, the concentration of sodium hydroxide is 2.0-2.2%, and the concentration of sodium hexametaphosphate is 10 Kg per ton of carbon; carrying out desorption electrolysis to extract gold, silver and copper by adopting a method of sodium cyanide + sodium hydroxide + sodium hexametaphosphate + high temperature and high pressure + ultrasonic wave to obtain high-copper-silver-gold mud and desorption electrolysis lean carbon; t |
