[Introduction]: Gold CIP process adsorbs gold from cyaniding pulp by active carbon including 7 steps: leaching pulp preparation, cyaniding leaching, carbon adsorption, gold loaded carbon desorption, pregnant solution electrodeposit, carbon acid regeneration, and leaching pulp.
[Improvement]: There are two kinds of ore suitable for the gold CIP system: one is flotation gold concentrate, amalgamation, and gravity tailings; the other is mudded oxidized ore.
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.
