activated carbon for gold recovery
For most clients, coconut shell activated carbon will be the best choice. With the high hardness and abrasion resistance, it can provide the best adsorption from aqueous cyanide solutions in CIP, CIL and CIC systems.
Adsorptive Capacity (known as K-value)
Often called loading capacity, the adsorptive capacity of activated carbon refers to how much the activated carbon can adsorb. Adsorptive capacity is linked to the physical and chemical properties of the activated carbon.
Adsorption Rate (known as R-value)
The rate of adsorption is also largely affected by both physical and chemical properties of the activated carbon.
Mechanical Strength and Wear Resistance/Hardness
Mechanical strength is important in reducing losses because of attrition. Attrition is the breakdown of material into fines. Not only does this result in carbon loss, but it also causes a loss in recoverable gold.
Particle Size Distribution
Particle size distribution is another key factor in choosing an activated carbon for gold recovery, as it is largely linked to adsorption rate.
Coconut shell-based carbons are the most commonly selected type of activated carbon for gold recovery. This type of carbon boasts numerous characteristics that make it ideal for use in gold recovery, including superior hardness and pore structure.
Application-Activated carbon for gold recover
Coconut shell activated carbon system coconut shell raw materials to produce better activated carbon, it is a grain of irregular broken charcoal, high strength, saturated after repeated regeneration, high adsorption capacity, low resistance is its salient features, coconut shell activated carbon For drinking water, industrial water decolorization, deodorant, remove organic matter. Gas-phase adsorption often used coconut shell granular activated carbon, usually by the air through the activated carbon layer adsorption. According to the state of the activated carbon layer in the adsorption device, the adsorption layer has several kinds of fixed layer, moving layer and flowing layer.
Activated carbon is recognized as the most high quality porous carbon material. Due to its high development porous structure and huge specific surface area, activated carbon is very strongly adsorbing. Activated carbon can also be impregnated with chemicals to produce impregnated activated carbon. Thus it is not only used as an excellent adsorbent ,but also used as a catalyst or catalyst carrier.It is widely used for drinking water, pure water, wine, beverage, industrial wastewater purification, decolorization, dechlorination, deodorant; Also can be used in oil refining industry to take off the mercaptan; And can be used in food, waterworks, power plants, nuclear power, medical, mining, metallurgy, petrochemical, steel, tobacco, fine chemical industry, etc.
