A Gold Refining Machine (Tumbler Type) is an advanced technology used for refining gold with higher efficiency, safety, and purity compared to traditional methods. It is widely adopted by large refineries and hallmarking centers.

🔹 Key Features of Tumbler Type Gold Refining Machine:

1. Technology:
• Works on Aqua Regia process (HCl + HNO₃).
• Unlike static reactors, the tumbler rotates, ensuring continuous movement of material for faster and uniform dissolution.
2. Advantages:
• High Purity Output: Produces 999.9 fine gold.
• Fast Processing: Up to 6–8 times faster than conventional static refining.
• Automation: Fully automatic system with PLC and HMI controls.
• Safety: Closed system prevents acid fumes from leaking; integrated fume treatment system (scrubber).
• Consistency: Uniform contact of gold with chemicals due to rotation.
3. Capacity Range:
• From 10 Kg per batch to 1000 Kg per batch (customizable as per refinery requirements).
4. Environmental Care:
• Equipped with fume scrubbers, filters, and ETP (Effluent Treatment Plant) for safe chemical disposal.
5. Applications:
• Large gold refineries.
• Jewellery manufacturers.
• Gold dore bar refiners.
• LBMA, BIS, NABL-certified refineries.
6. Additional Options:
• Automatic gold powder collection system.
• Integration with silver recovery system.
• DGFT, BIS, NABL, LBMA compliance setup available.

👉 In simple words: The tumbler type gold refining machine is the most advanced, efficient, and safest system to refine dore bars or scrap gold into 999.9 purity bullion.
