Before the adsorption of cyaniding pulp, remove the wood chips to avoid it adsorbs the gold and blocks the carbon screen.
Adding carbon in the leaching tank; the carbon absorbs gold becoming gold loaded carbon. After adsorption, carbon screen separates the carbon and pulp.
Under high temperature and pressure, gold loaded carbon separates gold mud and carbon in closed system.
After simple pickling and impurity removal, the gold ingots are obtained.
Under the high temperature and pressure, this system has advantages of no cyanide, automatic controlling, high efficiency, fast and low energy consumption.
High Efficiency: When the grade of gold loaded carbon reaches 3000g/t, desorption rate can reach more than 96%.
Fast: due to the high temperature and pressure, the time of desorption electrolysis is 12 hours shortened by 50-70%.
Low energy consumption: due to the same temperature and fast working, the energy consumption is 1/2-1/4 of regular system.
No cyanide: without adding NaCN in desorption solution, low cost and no pollution.
High grade gold mud, extract gold mud easily.
Automatic control: installed level liquid control system, temperature control system, automatic control system.
Safety: With three security measures, system intelligent, automatic limit pressure and pressure release mechanism, safety valve.
