Premium Grade Water Milled High Hardness Coconut Granule Activated Carbon for Gold Recovery/Extraction/Adsorption/Mining
Introduction
The product is a kind of apricot activated carbon used for gold recovery.The production processes are accomplished by using one combination of the following steps:
1.) Carbonization: Material with carbon content is pyrolyzed at
temperatures in the range of 600–900 °C, in absence of oxygen
(usually in inert atmosphere with gases like argon or nitrogen)
2.) Activation/ Oxidation: Raw material or carbonised material is
exposed to oxidizing atmospheres (carbon monoxide, oxygen, or
steam) at temperatures above 250 °C, usually in the temperature
range of 600–1200 °C. The product is also designed to comply with
all the applicable provision of ASTM standard for coconut activated
carbon.
Applications
It is mainly used for gold recovery.

Advantages
The gold cyanidation process is a primary method of gold beneficiation. Activated carbon is a critical component in the beneficiation of gold ore, allowing this widespread process to occur because of its ability to recover gold from the gold-cyanide complex.
Depending on the deposit, some silver ores may also be processed via cyanidation. Here too, activated carbon is the catalyst for recovery of this precious metal.
