The gold mine CIP process is a non-filtered cyanide carbon pulp extraction process that uses activated carbon to directly absorb and recover gold from cyanide pulp. , de-gold carbon recycling, leaching pulp treatment and other seven operating stages.
Before the adsorption of cyaniding pulp, remove the wood chips to avoid adsorbing the gold and blocking the carbon screen.
Adding carbon in the leaching tank; the carbon absorbs gold becoming gold-loaded carbon. After adsorption, a carbon screen separates the carbon and pulp.
Under high temperature and pressure, gold-loaded carbon separates gold mud and carbon in a closed system.
After simple pickling and impurity removal, the gold ingots are obtained.
Under the high temperature and pressure, this system has advantages of low cyanide, automatic controlling, high efficiency, fast and low energy consumption.
High Efficiency: When the grade of gold-loaded carbon reaches 3000g/t, the 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 the 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 intelligence, automatic limit pressure, and pressure release mechanism, safety valve.
Xinhai Tanzania Gold Mining Plant Project mainly adopts the carbon slurry adsorption method, and uses activated carbon to directly absorb and recover gold from cyanide pulp. The gold mud is obtained by the motor, and the de-gold carbon is circulated to the seven stages of leaching the pulp.
Finally, the daily processing capacity of 500t/d (including mining and beneficiation) ore will be obtained, and the gold concentrate with a recovery rate of up to 92.5% will be obtained.
