1. PAINPOINT DRIVEN OPENING

Managing a gold processing operation presents persistent challenges that directly impact your bottom line. Are you contending with inconsistent recovery rates due to inefficient separation? Is excessive downtime for maintenance and liner replacement cutting into your production schedule? Are you facing rising operational costs from high energy consumption and water usage? Furthermore, does the complexity of your current setup require highly specialized operators, creating staffing vulnerabilities? These issues translate to tangible losses: every percentage point of unrecovered gold and every hour of unplanned downtime represents significant forgone revenue. The central question for plant managers is how to achieve higher throughput and recovery while controlling operational expenses and simplifying maintenance.

2. PRODUCT OVERVIEW

This datasheet details our advanced line of Centrifugal Gold Concentrators, a critical component for the gravity separation stage in hard rock and alluvial gold recovery circuits. This equipment is engineered to maximize the capture of fine gold that traditional methods often miss.

Operational Workflow:
1. Feed Introduction: Slurry, typically from a grinding circuit or screening plant, is continuously fed into the rotating concentrator bowl.
2. GForce Separation: High rotational speed generates centrifugal force, packing heavier gold particles against the collection grooves or riffles, while lighter gangue material is fluidized and washed away.
3. Concentrate Retention: Gold and other heavy minerals are trapped within the bowl's designed retention system.
4. Automatic/Manual Discharge: Depending on the model, concentrated material is either automatically discharged at set intervals or manually cleaned after a scheduled batch cycle.
5. Tailings Disposal: The waste tailings exit the machine for further processing or disposal.

Application Scope & Limitations:
Scope: Ideal for recovering free gold >30 microns, as a primary concentrator in alluvial operations or as a secondary/tertiary concentrator in hard rock mills. Effective on both eluvial and placer deposits.
Limitations: Not suitable for chemicalbound (refractory) gold or ultrafine (<20 micron) particles without preclassification. Feed particle size and slurry density must be controlled within specified parameters for optimal performance.

3. CORE FEATURES

Variable Speed Drive | Technical Basis: Frequencycontrolled electric motor | Operational Benefit: Operators can precisely adjust Gforce to match feed grade and particle size distribution in realtime for optimal recovery | ROI Impact: Field data shows a 515% increase in fine gold recovery compared to fixedspeed units, maximizing yield from existing ore.
CeramicLined Concentrate Bowl | Technical Basis: Highalumina ceramic wear surfaces | Operational Benefit: Exceptional abrasion resistance extends service life 3x longer than polyurethane liners in highsilica feeds, reducing changeout frequency | ROI Impact: Cuts longterm parts inventory costs and labor hours dedicated to liner replacement, lowering cost per operating hour.
Automated Discharge System | Technical Basis: Programmable logic controller (PLC) with timer/sensor activation | Operational Benefit: Enables unattended operation during shift cycles with consistent concentrate removal, reducing operator intervention | ROI Impact: Improves overall plant throughput efficiency and allows personnel reallocation to other critical tasks.
LowPressure Feed System | Technical Basis: Optimized feed cone design and inlet geometry | Operational Benefit: Requires only standard slurry pump pressure (1025 PSI), eliminating the need for specialized highpressure pumps | ROI Impact: Reduces ancillary equipment capital cost and associated energy consumption by up to 30% for the concentration stage.
Modular Frame Design | Technical Basis: Bolttogether, preengineered steel structure | Operational Benefit: Simplifies transport to remote sites and allows for easier reconfiguration or expansion within the plant layout | ROI Impact: Reduces installation time and cost by approximately 25%, getting your operation to revenue generation faster.

6. APPLICATION SCENARIOS

Hard Rock Mill – Gravity Circuit Optimization

| Challenge:| A sulfide ore mill was losing significant fine free gold to the flotation tailings due to an outdated gravity circuit with low recovery below 100 mesh. |
| Solution:| Two centrifugal gold concentrators were installed as tertiary concentrators, processing the combined concentrate from shaking tables and spirals.| Results:| Within one quarter, overall plant recovery increased by 2.8%. The concentrators paid for themselves in under nine months through additional recovered ounces, with markedly lower operating costs than the previous jig system they supplemented.

Alluvial/Placer Mining Operation

| Challenge:| A largescale placer operation needed higher throughput and more consistent performance than their legacy sluice systems offered, especially during fluctuations in feed grade.| Solution:| A battery of four centrifugal concentrators was deployed in parallel as primary roughing units after trommel scrubbing.| Results:| The operation achieved a consistent +95% recovery rate across variable feed conditions, with throughput increased by over 35%. The automated discharge reduced labor requirements per tonne processed by an estimated two manhours.
