Coconut Shell Activated Carbon Making Process


Category: Cyanidation Equipment
  • Description

Description

Coconut shell activated carbon is made of high-quality coconut shells from Southeast Asian countries such as Indonesia and Malaysia as raw materials, and is activated and finely processed by carbonization. Coconut shell activated carbon is black in appearance, granular, has high wear resistance, fast adsorption speed, large adsorption capacity, easy desorption, and can be regenerated repeatedly. It is widely used in the gold extraction process of carbon slurry method and heap leaching method.

Activated Carbon or Activated Charcoal - Coconut Shell Activated Carbon Making Process

Coconut shell activated carbon has strong adsorption to gold ions in cyanide leach solution, and the adsorption speed is very fast. The amount of gold loaded on activated carbon depends on the gold content in the leach solution, and the gold load can be as high as 15kg/t. Usually, there are two ways to recover gold from gold loaded carbon: one is to roast gold loaded carbon and smelt it at high temperature to obtain gold,the other is to desorb the gold cyanide complex with a desorption solution, and then obtain pure gold by electrolysis and other methods. The coconut shell activated carbon particles produced by our factory are full and uniform, there is no need for pre-ground after entering the factory, and it can be used after washing.

Coconut shell activated carbon should be prevented from being mixed with hard substances during transportation, and should not be stepped on to prevent the carbon particles from being broken and affecting the quality of use. And water immersion must be prohibited, because a large amount of water will fill the active air after immersion, making it impossible to use normally.

Unique properties of coconut shell activated carbon
Coconut shell-based activated carbon has its advantage over its other forms being:

  • Consistent performance with the higher retention rate
  • Excellent microporous structure with extensive internal structure
  • Higher surface area
  • Hard and durable
  • Low dust, ash content, and impurities
  • Low-pressure drop and an optimized density
