YX-STL Series Gold Centrifugal Concentrator with 10-60 TPH Capacity and ≥95%

The YX-STL series gold centrifugal concentrator represents a breakthrough in mercury-free gold recovery technology specifically engineered for small to medium scale mining operations. This equipment harnesses centrifugal force to achieve exceptional separation efficiency for fine-grained gold particles that traditional gravity methods struggle to recover. Designed with the specific requirements of artisanal and small-scale miners in mind, it delivers professional-grade gold recovery without relying on mercury amalgamation, fully complying with the Minamata Convention on Mercury. The robust yet compact modular construction enables rapid deployment in remote high-altitude mining regions across Latin America, Africa, and Southeast Asia.

• Mercury-Free Processing: Fully compliant with the Minamata Convention, the concentrator uses pure physical centrifugal separation to extract gold, eliminating the environmental and health hazards associated with mercury amalgamation. This feature is particularly critical for Colombian and Andean region miners facing increasingly strict environmental enforcement.
• Exceptional Fine Gold Recovery: Engineered to capture gold particles down to 0.01mm with a recovery rate exceeding 95 percent. The optimized fluidization water system and precisely machined riffle grooves ensure that ultra-fine gold that conventional sluice boxes and jigs miss is consistently retained in the concentrate.
• Modular Skid-Mounted Design: Pre-assembled on a robust steel skid frame, the entire unit can be transported to remote mountainous mining sites and operational within hours of arrival, minimizing installation downtime and civil engineering costs.
• Adjustable Processing Parameters: Variable speed drive control for drum rotation (60-200 RPM), independently regulated fluidization water flow, and adjustable concentrate cycle duration allow operators to fine-tune performance for specific ore characteristics including particle size distribution, mineral density, and clay content.
• Low Water Consumption: The closed-loop water design with integrated recirculation capability reduces freshwater demand by up to 60 percent compared to conventional sluice-based systems, making it suitable for water-scarce mining regions.
• Heavy-Duty Wear Protection: The concentrate collection zone features replaceable polyurethane wear liners and the drum interior is coated with abrasion-resistant ceramic composite, ensuring service life exceeding 15,000 operating hours under continuous production conditions.

The YX-STL centrifugal concentrator is ideally suited for placer gold deposits, alluvial gold mining operations, weathered rock gold deposits, and hard rock gold grinding circuit tailings scavenging. It performs exceptionally well in the Antioquia, Choco, and Bolivar gold belts of Colombia where mercury-free alternatives are mandated. The equipment also integrates seamlessly as the primary recovery stage in a combined gravity-flotation flowsheet for polymetallic gold ores, or as a scavenger unit recovering gold from flotation tailings that would otherwise report to the tailings dam. For exploration and pilot-scale testing, the YX-STL20 model provides reliable grade and recovery data for feasibility studies and resource estimation.

Each concentrator undergoes factory acceptance testing at rated capacity before shipment.
