What is a Gold Purification Activated Carbon Making Machine?

A Gold Purification Activated Carbon Making Machine is industrial equipment used to produce activated carbon tailored for the gold recovery process. This activated carbon must have:

• High adsorption rate for gold ions
• Low impurity content
• Uniform granule or pellet size
• Resistance to harsh chemical environments

The machine integrates:

• Carbonização
• Activation (steam or chemical)
• Granulation
• Cooling and packaging

Raw Materials for Gold Purification Activated Carbon

Common raw materials include:

• Coconut shells – microporous, high hardness, and excellent adsorption
• Coal – anthracite or bituminous coal with high carbon content
• Bamboo and wood – biomass options with mesoporous structures
• Palm kernel shells – renewable and hard material suitable for gold adsorption

Pre-treatment involves:

1. Crushing to uniform particle size
2. Drying to reduce moisture below 10%
3. Screening to remove impurities

Working Principle of Gold Purification Activated Carbon Making Machine

Step 1: Crushing and Drying

Raw materials are crushed and dried to ensure uniform particle size and moisture control for efficient carbonization.

Step 2: Carbonization

Crushed material is heated in a carbonization furnace under low-oxygen conditions. Volatile compounds are removed, leaving carbon-rich char suitable for activation. Rotary kilns or batch furnaces can be used depending on production capacity.

Step 3: Activation

• Steam Activation – high-temperature steam reacts with carbon char to create micropores for gold adsorption
• Chemical Activation – chemicals such as KOH or H₃PO₄ enhance the surface area and adsorption capacity

Step 4: Granulation and Screening

Activated carbon is granulated into uniform sizes or pellets to ensure optimal performance in gold leaching tanks. Screening ensures consistent particle size and quality.

Step 5: Cooling and Packaging

Finished activated carbon is cooled to prevent oxidation, stabilized, and packaged for gold purification applications.
