The equipment is new complete equipment used in gold trade to recover gold from the gold-carrying carbon. It is suitable for desorption and electrolysis of gold-carrying carbon with different grades. The desorption is an intermixture of 1~2% sodium cyanide and 1~4% sodium hydroxide. The desorption solution is pumped to the heater by circulating pump and heated to the desired temperature. Then the solution flows downward to the bottom of desorption column, through the gold-carrying carbon in the column and upward to the top of it. During flowing, the solution strip gold from the carbon (at this stage the solution containing gold is called as pregnant solution). The pregnant solution runs out from the top of the column and into the electrolytic cell. In cell, the gold in the solution is electrically deposited in the steel wool of the cathode frame, and the rest (called as lean solution) flows back to desorption solution cell and recycled.
The gold mud containing rich gold and silver is taken out of desorption cell and transported to the separation section.
