Coconut Shell Activated Carbon for Gold Refining
Yihang coconut shell activated carbon for gold refining is made from high-quality coconut shell, refined by physical method and high-temperature steam activation process. The coconut shell activated carbon for gold recovery has uniform particle size, high mechanical strength, and strong adsorption. It is manufactured by special processes such as water milling.
Coconut shell activated carbon for gold refining is widely used in the extraction of gold by carbon slurry method and heap leaching method. The coconut shell activated carbon for gold recovery adopts a special process, which has carried out high-strength shaping of the activated carbon particles, and almost all of the particles in the particles, such as needle-shaped, pointed, angular and easy-to-wear parts, are removed. The particle shape is full and uniform, which greatly improves the abrasion resistance of the product. After receiving the goods, there is no need for pre-grinding, and it can be used directly after washing with water. It is suitable for gold mining production in modern gold mines.
The hardness and proper pore size distribution of the coconut shell activated carbon used for gold recovery ensure abrasion resistance (preventing the loss of gold with carbon) and high gold absorption in a single adsorption cycle.
The coconut shell activated carbon used for gold refining has the following advantages:
- There are many pore structures and large specific surface area.
- High wear resistance.
- Fast adsorption speed and large adsorption capacity.
- Super hardness, not easy to be crushed.
- Low loss, can be used repeatedly.
- Iodine value: The lowest iodine value of coconut shell activated carbon used for gold refining is 950mg/g, and can generally reach more than 1000-1100mg/g. The bulk density of good quality coconut shell activated carbon should be 1000mg/g, and the impact toughness should be Around 90%.
- Strength: The coconut shell activated carbon used for gold refining has a strength ≥98%, which has higher abrasion resistance and compressive strength than ordinary activated carbon.
- Specific surface area: The specific surface area of coconut shell activated carbon used for gold recovery is ≥1400?/g, so that there is more adsorption space. The specific surface area of conventional nut shell activated carbon can only reach 1100?/g. This is the advantage of coconut shell activated carbon over other activated carbons.
