Activated carbon gold leaching carbonized coconut shell China

1.What is the activated carbon in gold leaching?
 

Activated carbon is a highly carbonized material with tens of thousands of micropores, which has a very large surface area and strong ability to adsorb substances. 
 

Activated carbon can adsorb metal ions. When the mixture of gold cyanide ions adsorbed by activated carbon approaches saturation, adding a reducing agent can reduce it to metal
 

2.Which kinds of gold project activated carbon can be used?

All kinds of gold leaching plant can be used , such as gold cil / cip plant , gold heap leaching plant , gold pool leaching plant , and small scale gold processing plant. In market , usually together with gold ore dressing agent
 

3.Why need activated carbon in gold leaching?
 

After adsorption of gold by activated carbon,  heat it and add reducing agents, will separate the gold from the activated carbon, and then melted it to obtain pure gold.

4.Which kind of activated carbon is most suitable in gold leaching recovery?
 

Worldwide, the most popular is coconut shell activated carbon, which has a large specific surface area and strong adsorption capacity, making it very suitable for adsorbing gold in gold  leaching recovery.
 

Our activated carbon raw material is coconut shell, grown from coconut trees that have been growing for more than 5 years. Not only effectively improve the gold recovery rate, but also reduce production costs.

6.Steps of activated carbon in gold leaching recovery
 

1.pour the golden liquid into the activated carbon tanks:then stir for a period of time to allow the gold to fully contact the activated carbon, wait for the gold to be adsorbed by the activated carbon, and pick up the activated carbon from the tank
 

2.Clean  activated carbon : Collect activated carbon containing gold and clean it with water or detergent to remove surface impurities.
 

2. Metal reduction: Place the collected activated carbon in a furnace and reduce the metal by heating and adding a reducing agent. The selection of smelting and reducing agents depends on the materials and processes being processed.
 

3. Separation of gold: During the reduction process, metallic gold is reduced by a reducing agent and can be separated from activated carbon. Activated carbon needs to be removed from the furnace and screened on a sieve to remove useless impurities, leaving only metal particles containing gold.
 

4. Re melting: Re melting the gold in the activated carbon to remove any residue and obtain pure gold.

7.Features & benifits of coconut shell activated carbon

1.Coconut shell gold activated carbon is made from coconut shell as raw material, using converter activation process and refined through wind selection, crushing, screening and other treatments. It has high strength, uniform particle size, developed microporous structure, strong selective adsorption of gold cyanide complex, easy to decompose and can be regenerated multiple times, and can be reused repeatedly.

2.The adsorption capacity of coconut shell activated carbon comes from the special structure of its forest resources, which have a large surface area and pore structure, which can greatly increase the adsorption surface area.

3.The pore structure and high strength of coconut shell activated carbon enable it to withstand mechanical wear and high flow rates when processing gold containing solutions, ensuring long-term stable adsorption performance.
 

4.Its high surface area and uniform pore size distribution help improve gold absorption efficiency and reduce gold loss
