Product Introduction
Centrifugal gold concentrator is an advanced gravity separation machine designed for high-efficiency recovery of fine free gold and other precious or heavy metals from alluvial, hard rock, and tailing materials.
Built with a robust structure and reliable performance, this centrifugal gold concentrator is widely used in gold mining projects across Africa, Southeast Asia, and South America.
Application Scenarios
Alluvial gold wash plants
Hard rock gold processing lines (after ball mill grinding)
Gold tailings recovery
Artisanal and small-scale mining (ASM)
Laboratory and pilot-scale testing
Heavy metal concentration in rare metal mining

Working Principle
The centrifugal gold concentrator uses the principle of high-speed centrifugal force to enhance the gravitational separation of heavy particles. Gold and other heavy minerals are captured in the concentration cone, while lighter materials are discharged.
The centrifugal gold concentrator is ideal for recovering:
Fine free gold particles (< 100 microns)
Placer gold and alluvial gold
Sulfide-associated gold (after grinding)
Heavy minerals (tantalite, wolframite, etc.)
Advantages
High Recovery Rate
Up to 90–95% recovery for free gold, even down to 30–40 microns.
Eco-Friendly Process
No chemicals or cyanide required — clean gravity separation.
Low Water & Power Consumption
Efficient use of resources; suitable for remote or off-grid sites.
Automatic & Manual Models
Choose from batch-type or continuous automatic discharge models.
Simple Operation & Maintenance
One-button start; easy to clean concentrate bowl.
