1. PAINPOINT DRIVEN OPENING

Managing a gold processing operation means contending with persistent challenges that directly erode profitability. When evaluating gold mining equipment, plant managers and engineering contractors consistently face several critical issues: inconsistent recovery rates due to inefficient separation, leading to measurable gold loss in tailings; excessive downtime from equipment wear in abrasive, highclay, or sulfiderich ore bodies; and rising operational costs from high water consumption, energyintensive processes, and frequent component replacement. Are you achieving maximum payable gold recovery from your complex ore? Is your current circuit’s availability under 90%, creating costly production gaps? How much capital is tied up in maintenance inventories and unplanned repairs? The right gold mining equipment must provide a definitive answer to these questions by delivering reliable, efficient, and economically optimized mineral processing.

2. PRODUCT OVERVIEW

This product line encompasses advanced centrifugal concentrators for gravity separation, a critical stage in modern gold mining equipment circuits. Designed for both primary recovery and scavenging applications, this system enhances overall plant yield by capturing fine gold that traditional methods miss.

Operational Workflow:
1. Feed Preparation: Slurry from the milling circuit is classified and screened to optimal particle size.
2. Concentration: The slurry is introduced into a rapidly rotating drum, where centrifugal force amplifies gravity, separating highdensity gold particles from gangue material.
3. Collection: Concentrated gold collects in internal grooves or riffles.
4. Automatic Discharge: At programmed intervals, the system halts rotation and flushes the concentrate to a secure collection point, minimizing manual handling.
5. Tailings Disposal: Depleted slurry (tailings) exits continuously for further processing or disposal.

Application Scope & Limitations:
Scope: Highly effective for freemilling alluvial and hard rock ores; excellent as a scavenger unit after flotation or cyanidation circuits; suitable for operations ranging from 10 to 200 tons per hour per unit.
Limitations: Performance diminishes on ultrafine (<10 micron) or fully locked (refractory) gold without pretreatment. Requires consistent feed density and particle size distribution for optimal efficiency.

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 characteristics (e.g., clay content, gold granulometry), maintaining peak recovery without shutdowns. | ROI Impact: Field data shows a 38% increase in recovery over fixedspeed units when processing variable ore blends.

CeramicLined Fluidization Cones | Technical Basis: Advanced wearresistant ceramic components in highabrasion zones | Operational Benefit: Eliminates metaltoore contact in critical wear areas, drastically reducing maintenance frequency and preventing iron contamination of concentrate. | ROI Impact: Extends service life by over 400% compared to polyurethane standards, reducing spare parts cost and downtime.

Programmable Automatic Discharge Cycle | Technical Basis: PLCcontrolled sequencing of concentrate flushing | Operational Benefit: Removes operator dependency for timing, ensures consistent concentrate grade, and allows unattended operation during shift changes or breaks. | ROI Impact: Improves security of recovered gold and can reduce labor requirements for concentration cleanup by up to 70%.

LowPressure HydroWater Wash System | Technical Basis: Optimized hydraulic design for efficient fluidization with minimal water pressure | Operational Benefit: Achieves effective bed fluidization and concentrate cleaning using up to 30% less process water than previousgeneration designs. | ROI Impact: Lowers water pumping costs and reduces load on water recovery circuits in waterconstrained sites.

Modular Bowl Design | Technical Basis: Interchangeable concentrating bowl assemblies | Operational Benefit: Enables rapid changeover (<2 hours) between bowl types optimized for different particle size ranges (e.g., coarse vs. fine gold). | ROI Impact: Maximizes plant flexibility; one machine can serve multiple duty points by swapping bowls instead of purchasing separate specialized units.

6. APPLICATION SCENARIOS

Alluvial Placer Operation – High Clay Content Ore

Challenge: A largescale placer mine experienced severe blinding of traditional sluices due to high clay content, causing significant fine gold loss (>35%) and requiring constant manual cleaning.
Solution: Implementation of twostage centrifugal concentrators as the primary recovery method after scrubbing.
Results: Consistent recovery rates above 88% were achieved despite variable clay levels; automatic discharge eliminated manual cleanup labor; overall site yield increased by 22%.

Hard Rock Mill – Scavenger Duty PostGrinding

Challenge: A CIP/CIL plant identified persistent gravityrecoverable gold reporting to leach tails despite an existing gravity circuit, representing a direct revenue loss.
Solution: Installation of a highG centrifugal concentrator on the cyclone underflow stream as a dedicated scavenger unit before leaching.
Results: The unit recovered an additional 0.8 g/ton of gold from tailings streams previously considered barren; payback period was calculated at under six months based on incremental recovered metal value.
