gold refining electrolysis machine

The high temperature and high-pressure desorption method is to install thegold-loaded carbonin a pressure vessel, and mix the solution with 0.4% to 1% NaOH and 0.1% NaCN, heat temperature to 130 to 160 ° C, under the pressure of 3.6 to 5.9 kg/cm2. Within 2 to 6 hours, thegoldand silver desorption rates ofgold-loadedcarbon exceeded 90%.
