In recent years, the adsorption of coconut shell activated carbon plays a vital role in the gold extraction process. How to buy good coconut shell gold activated carbon is an important criterion for measuring the quality of gold purification. In the process of gold extraction, the adsorption of coconut shell activated carbon is mainly used.

What are the technical requirements for coconut shell activated carbon for gold purification?

1. Coconut shell gold activated carbon material: Coconut shell activated carbon is made of high-quality coconut shells and refined by physical methods and high-temperature steam activation processes. Coconut shell activated carbon for gold has uniform particle size, high mechanical strength, strong adsorption capacity, and is manufactured by special processes such as water grinding. It has good wear resistance and high adsorption performance. It is suitable for modern gold mining production. It is mainly used for the separation and extraction of precious metals in the gold metallurgical industry by heap leaching or carbon slurry.

2. Coconut shell gold activated carbon iodine value: The lowest iodine value of golden coconut shell activated carbon is 950mg/g, and it can generally reach 1000-1100mg/g or more. The bulk density of good quality coconut shell activated carbon should be 1000mg/g, and the impact toughness should be around 90%.

3. Specific surface area of coconut shell gold activated carbon: The specific surface area is ≥1400㎡/g, so there is a larger adsorption space. The specific surface area of conventional fruit shell activated carbon can only reach 1100㎡/g. This is the advantage of using coconut shell activated carbon.

4. Strength of coconut shell gold activated carbon: Strength is ≥97%, which has higher wear resistance and compressive strength than ordinary activated carbon.

5. Specifications of coconut shell gold activated carbon: The selected particle size is generally 10-24 mesh, moisture ≦5, ash content: ≦10%; because the particles are not easy to flow, the residues such as organic compounds in the water are not easy to block in the coconut shell activated carbon filter layer, and it has strong adsorption capacity and fast filtration speed.

6. Coconut shell gold activated carbon is economical and durable: Coconut shell gold activated carbon has a strong characteristic of regeneration after saturation. High-quality gold purification coconut shell activated carbon has a black appearance and is granular. It has a developed pore structure, a huge specific surface area, strong adsorption capacity, high wear resistance and pressure resistance, small bed resistance, easy regeneration, economical and durable, and can operate continuously in the tower.

Facts have proved that the above technical indicators need to be achieved when purchasing coconut shell activated carbon for gold purification in order to achieve the best purification effect, which is the highest realm of coconut shell gold activated carbon! Coconut shell gold activated carbon is also suitable for a variety of precious metal purification industries and has won the support and favor of many industries.
