1. Simplify the process and reduce costs:
The CIP process eliminates the solid-liquid separation operation and simplifies the process flow by adsorbing the gold-cyanide complex through activated carbon.
This simplification can save 25% to 50% of the infrastructure cost and 5% to 30% of the production cost. For oxidized muddy gold-bearing ore, the savings in infrastructure cost and production cost are particularly obvious.
2. Improve the gold recovery rate:
The liquid phase gold content in the residual slurry discharged by the carbon-in-slurry process is generally 0.01g/m³, which has a higher gold recovery rate than the conventional cyanidation method.
3. Expand the application scope of the cyanidation method:
The CIP process can also effectively treat gold-bearing ores with poor sedimentation and filtration performance, and is especially suitable for treating gold-bearing mineral raw materials with muddy and difficult solid-liquid separation.
4. Reduce cyanide consumption:
The precious liquid obtained by desorption of gold-bearing carbon in the CIP process is usually electrolytically precipitated, and there is no requirement for the cyanide content in the precious liquid, so it is conducive to reducing the consumption of cyanide.
5. Produce gold ingots with higher purity:
The carbon slurry process uses electrolytic deposition to extract gold. The purity of the gold mud is high, which can reduce the flux consumption during smelting and shorten the smelting time. The loss of gold in slag and flue gas is small, so that gold ingots with higher purity can be obtained.
6. Strong adaptability:
The CIP process is not only suitable for sulfide ores and oxide ores, but also for mixed ores, showing strong adaptability.
7. Simple operation and low investment:
The CIP process is simple to operate, with less equipment, short process, and fewer operators, so it saves investment and low cost.
