Activated carbon is known effective in purification in removing organic impurities. Which is why, many industries such as water filtration, gas filtration, and gold recovery in mining operations are using activated carbon.
According to Wikipedia, activated carbon or activated charcoal is a form of carbon processed to have small, low-volume pores that increase the surface area available for adsorption or chemical reactions.
Which is why, the uses of activated carbon is essential for gold industry to provides excellent process performance, minimal attrition loss and minimal maintenance problems.
HOW DOES THE ACTIVATION CARBON WORKS DURING THE GOLD CYANIDATION PROCESS?
Activated carbon has become a standard in industry that is efficient to separate gold from cyanide leaching solutions through the three basic systems;
Carbon in Pulp
Carbon in pulp or CIP processing occurs when the ore is finely ground and the gold is soluble using a cyanide leach inside the tank and the activated carbon are added to the leached slurry and the activated carbon will adsorbs the gold from the slurry solution and then removed from the slurry by coarse screening.
Carbon in Leach
Carbon in leach or CIL process occurs when the activated carbon is added in leach, with gold adsorption occurring with gold dissolution by the cyanide solution. The activated carbon is added before any leaching occurs.
Carbon in Column
Carbon in Column or CIC is having a different process than the two previous methods. Pouring the gold cyanide solution into massive columns packed with activated carbon is occurs after the leaching process.
CHARACTERISTICS OF ACTIVATED CARBON FOR GOLD RECOVERY
There are various types of activated carbon within the field of gold for different applications with unique characteristics.
Adsorptive Capacity (known as K-value)
This refers to how much the activated carbon can absorb.
Adsorption Rate (known as R-value)
The rank of adsorption is influence by physical and chemical properties of the activated carbon
Mechanical Strength and Wear Resistance/Hardness
Using the mechanical strength to reduce the losses from attrition which can cause carbon loss and cause the loss in recoverable gold
Particle Size Distribution
It is another key factor in choosing activated carbon for gold recovery which linked to the adsorption rate.
