1. PAINPOINT DRIVEN OPENING

Are escalating operational costs and unpredictable downtime eroding your gold recovery margins? Inconsistent feed rates, premature component wear in abrasive environments, and inefficient separation of fine gold particles directly impact your plant’s bottom line. Each hour of unscheduled maintenance represents significant lost revenue, while suboptimal recovery rates leave valuable material in your tailings. Are you managing high energy consumption per ton processed? Is your current equipment struggling with variable ore grades, forcing a tradeoff between throughput and recovery efficiency? These are the daily challenges that compromise the profitability of a commercial gold mining operation.

2. PRODUCT OVERVIEW

This product line encompasses highcapacity centrifugal concentrators engineered for the continuous recovery of free gold, particularly fine gold that is often lost in traditional sluicebased systems. The operational workflow is designed for integration into your existing plant: (1) Ore slurry is introduced under controlled pressure into a rotating drum. (2) Centrifugal force pins heavier gold particles against the drum’s riffled lining while lighter gangue material is fluidized and washed out. (3) After a programmed cycle time, the concentrator automatically decelerates, and an internal rinse cycle discharges the concentrated goldbearing product for further upgrading. This equipment is specifically effective for alluvial/placer operations and hard rock mill circuits recovering liberated gold >50 microns. It is not a primary crusher or grinding mill and requires feed material to be suitably classified and slurried.

3. CORE FEATURES

Variable Frequency Drive (VFD) Control | Technical Basis: Precision electromechanical speed regulation | Operational Benefit: Operators can finetune rotational speed in realtime to match changing ore density and feed grade, optimizing recovery without stopping the process. | ROI Impact: Field data shows a 515% increase in overall recovery rates from variable deposits, maximizing yield from every ton.

AbrasionResistant Composite Liners | Technical Basis: Engineered polymerceramic matrix formulation | Operational Benefit: Liners withstand continuous exposure to abrasive sands and slurries, significantly outperforming standard rubber or steel linings in wear life. | ROI Impact: Reduces liner replacement frequency by up to 300%, lowering parts inventory costs and maintenance downtime.

Automated Discharge Cycle | Technical Basis: Programmable Logic Controller (PLC) with timer/counter function | Operational Benefit: Eliminates manual stopping, rinsing, and restarting, ensuring consistent concentrate quality and allowing unattended operation during shift cycles. | ROI Impact: Reduces labor requirements for concentration duties by an estimated 70% per unit and prevents operator error leading to gold loss.

HighG Force Concentration Bowl | Technical Basis: Enhanced drum geometry and drive train delivering >200 G’s | Operational Benefit: Generates superior gravitational force to capture ultrafine gold particles that lowerG machines cannot retain effectively. | Operational Benefit: Expands the recoverable particle size range, directly reducing visible gold losses to tailings.

LowPressure Hydraulic System | Technical Basis: Closedloop hydraulic drive for bowl rotation | Operational Benefit: Provides smooth, hightorque startup under load with substantially lower heat generation and noise than direct gear drives. | ROI Impact: Improves energy efficiency by approximately 18% compared to legacy geardriven models and increases component lifespan in continuous duty applications.

6. APPLICATION SCENARIOS

Alluvial Placer Mining Operation – West Africa

Challenge: A largescale placer operation was experiencing significant fine gold loss in its trommel scrubber discharge due to fluctuating clay content blinding traditional sluices.
Solution: Installation of a battery of six highcapacity centrifugal concentrators in parallel to treat the primary classified slurry.
Results: Plantwide recovery efficiency improved from an estimated 68% to over 87%. The consistent concentrate produced reduced cleanup processing time by half.

Hard Rock CIP Mill Circuit – North America

Challenge: A mill sought to reduce its carboninleach load by recovering coarse free gold ahead of leaching circuits, thereby increasing overall plant throughput capacity.
Solution: Integration of two automated centrifugal concentrators into the grinding circuit’s cyclone underflow stream.
Results: An average of 18% of total monthly gold production is now recovered as free gold prior to leaching, reducing retention time requirements downstream and increasing mill throughput by 8%.
