Targeting Commercial Buyers, Plant Managers & Engineering Contractors: HighEfficiency Gold Mining Equipment for Maximum Yield and Minimum Downtime

1. Addressing Critical Operational Challenges in Gold Recovery

Are escalating operational costs and unpredictable yield compromising your project's viability? In gold mining, inefficiency directly erodes profit margins. Key challenges include:
Low Recovery Rates & Grade Variability: Inconsistent ore grades lead to unpredictable gold recovery, leaving valuable material in tailings. Industry estimates suggest poor separation can result in 515% revenue loss.
Excessive Downtime for Maintenance: Frequent breakdowns of critical processing equipment halt entire operations. Unplanned downtime can cost over $10,000 per hour in lost production and labor.
High Energy & Water Consumption: Gravity separation and leaching processes are resourceintensive. Energy and water costs can constitute 2530% of total operational expenses, squeezing profitability.
Complex Operation & Skilled Labor Shortages: Overly complex systems require specialized operators, leading to higher labor costs and increased risk of human error affecting consistency.

Is your current setup delivering the predictable throughput and recovery rates your financial model requires? The solution lies in equipment engineered for precision, durability, and operational simplicity.

2. Product Overview: Advanced Centrifugal Gold Concentrators

Our flagship centrifugal gold concentrators are engineered for the highvolume recovery of fine gold from alluvial and hard rock processing plants. This equipment enhances gravity separation efficiency, capturing gold particles that traditional methods like sluices or jigs often miss.

Operational Workflow:
1. Feed Preparation: Ore slurry is classified to optimal particle size (typically 6mm) and fed at a consistent density.
2. Centrifugal Concentration: The slurry enters a rapidly spinning drum, where centrifugal force amplifies gravity, separating highdensity gold from gangue material.
3. Continuous Concentration: Gold particles are trapped behind specifically designed riffles while lighter materials are fluidized and discharged as tailings.
4. Automated Concentrate Removal: A timed or sensorbased rinse cycle automatically discharges the goldrich concentrate into a collection bowl, minimizing manual intervention.

Application Scope: Ideal for both alluvial/placer operations and hard rock mill circuits as a primary concentrator or scavenger unit. Best suited for recovering free gold >75 microns.
Limitations: Not effective for chemicalbound (refractory) gold or ultrafine (<50 micron) particles without preclassification; requires consistent feed density for optimal performance.

3. Core Features: Engineered for Superior Performance

Enhanced GForce Control System

Technical Basis: Variable frequency drive (VFD) precisely controls bowl rotation to generate adjustable centrifugal force up to 200 Gs.
Operational Benefit: Operators can finetune Gforce in realtime to match changing feed grade and particle size distribution, maximizing recovery across varying conditions.
ROI Impact: Field data shows a consistent 812% improvement in fine gold recovery compared to fixedspeed units, directly increasing revenue.

LowPressure HydroRinse System

Technical Basis: Targeted lowpressure water jets fluidize concentrate during the automated discharge cycle.
Operational Benefit: Ensures complete cleaning of riffles without disrupting the settled heavy mineral bed or requiring manual highpressure hosing.
ROI Impact: Reduces cycle time by 40% and increases operational safety by eliminating manual cleaning inside a spinning bowl.

AbrasionResistant Composite Riffle System

Technical Basis: Riffles manufactured from polyurethaneceramic composite matrix offer superior wear life compared to standard rubber or steel.
Operational Benefit: Dramatically extends service intervals; riffle replacement is needed only after 3,0004,000 operational hours under standard abrasive conditions.
ROI Impact: Cuts spare parts inventory costs by 60% and reduces annual maintenance downtime by approximately 50 hours per unit.

Integrated Process Monitoring & Automation

Technical Basis: PLC with HMI touchscreen monitors motor load, feed pressure, bowl speed, and cycle times.
Operational Benefit: Provides operators with clear process visibility, enables automated operation sequences, and logs performance data for production analysis.
ROI Impact: Reduces operator training time by 30% and enables datadriven decisions to optimize overall plant recovery efficiency.

6. Application Scenarios

Alluvial Placer Operation in West Africa

Challenge: A largescale placer operation was losing significant fine gold (<100 mesh) to tailings using traditional sluices due to fluctuating feed grades and high clay content.
Solution: Implementation of two highcapacity centrifugal concentrators as primary recovery units after scrubbing and screening.
Results: Within one month of operation:
Overall site recovery efficiency increased from an estimated 70% to 89%.
Concentrate grade improved by a factor of over 300x versus feed grade,
Payback period on equipment was achieved in under four months based on recovered gold value.
