Activated carbon for gold extraction plays a crucial role in gold smelting, and with its unique adsorption properties, it has become an indispensable material in the gold extraction process. In this paper, Huamei carbon will discuss the advantages, principles, usage and market prospects of activated carbon for gold extraction, to show readers the charm of this amazing material.
Huamei gold extraction with activated carbon mainly carbone attivo in guscio di cocco and coal-based activated carbon and other types. Among them, coconut shell activated carbon has a large specific surface area, large microporous volume, fast adsorption speed, large adsorption amount of gold, better abrasion resistance, easy to reactivate and use. Commonly used properties of activated carbon for gold extraction are iodine adsorption value ≥950mg/g, particle size 6-16 mesh ≥90%, strength ≥97%, moisture ≤10%, filling density 450 - 550g/L and so on.
(I) High adsorption performance
Activated carbon for gold extraction is characterized by large specific surface area and large microporous volume. According to the data, the surface area of 1 gram of activated carbon is equivalent to the surface area of a soccer field, and such a large surface area makes activated carbon an ideal adsorbent. Its rich microporous structure is suitable for adsorption of certain inorganic complex ions from solution, including gold-cyanide complex ions. Since the cross-section of the carbon micropores is similar to the diameter of the gold-cyanide complex ions, the gold-cyanide complex ions need to undergo a slow diffusion process to be adsorbed. To enhance the diffusion process, the slurry is stirred sufficiently during the carbon slurry gold extraction process to facilitate the adsorption of gold by the activated carbon. This unique structure makes the activated carbon on the adsorption of gold, can effectively extract gold, play a key role in the gold extraction process.
(ii) Better abrasion resistance
In the carbon slurry process, activated carbon with better abrasion resistance shows greater resistance to abrasion. Activated carbon with greater strength can maintain lower loss under strong impact and grinding. On the other hand, activated carbon with less strength is easy to be abraded and thinned, and finally carries a large amount of adsorbed gold through the interstage sieve and loses with the tailings. For example, the commonly used activated carbon for gold extraction has a strength of ≥97%, which ensures the stability of the activated carbon in the process and reduces the loss of gold.
(iii) Easy to reactivate and utilize
When the activated carbon adsorbs a large number of impurities, it will lose its activity, and at this time, its adsorption capacity can be restored through acid washing, thermal regeneration and other methods. Activated carbon should be acid washed before regeneration to remove organic matter, in order to remove alkali metal oxides. Generally, the deactivated carbon is regenerated to remove organic matter after 3 to 5 cycles of acid washing, and then returned to the activated carbon adsorption section. This reduces the loss of carbon, saves electricity and has no effect on the adsorption rate. Through these methods, the activated carbon can be recycled, reducing the cost of gold extraction.
When selecting carbone attivo per il recupero dell'oro, key properties such as its strength, saturated gold loading capacity, adsorption speed and resolution rate need to be considered. Activated carbon with greater strength can show greater resistance to abrasion in the carbon slurry process flow and reduce the loss of gold. Activated carbon with high adsorption speed, high saturated gold loading capacity and high resolution rate can increase the efficiency and yield of gold extraction.
Overall, the principle of activated carbon for gold extraction is to realize effective adsorption and extraction of gold through its unique porous structure and chemical properties. This principle provides an efficient, economical and environmentally friendly method for gold smelting.
