1. PAINPOINT DRIVEN OPENING

Managing a gold processing operation requires balancing throughput, recovery rates, and operational costs. Inefficient or unreliable equipment directly impacts your bottom line. Are you facing these persistent challenges?
High Operational Downtime: Frequent mechanical failures in critical separation stages lead to unplanned stoppages, costing thousands per hour in lost production.
Suboptimal Gold Recovery: Inefficient separation technology fails to capture fine or coarse gold particles, leaving measurable value in your tailings and reducing overall yield.
Excessive Water and Energy Consumption: Outdated systems use disproportionate volumes of water and high horsepower, escalating utility costs and environmental management expenses.
High Maintenance Labor Costs: Equipment with complex designs or poor component accessibility demands excessive technician hours for routine servicing and repairs.
Inconsistent Performance in Variable Feed: Fluctuations in ore grade or particle size distribution cause performance drops, making output and recovery difficult to predict and optimize.

The right gold mining equipment is not just a purchase; it's a strategic investment in plant stability and profitability.

2. PRODUCT OVERVIEW

This catalog details our engineered range of Centrifugal Gold Concentrators. This equipment is designed for the gravity separation and concentration of free gold from ore streams. The operational workflow is a continuous cycle: 1.) Feed Preparation: Classified slurry is introduced into the rotating bowl. 2.) Centrifugal Concentration: Enhanced gravitational forces settle dense gold particles against the collection riffles while lighter gangue material is fluidized and expelled. 3.) Concentrate Collection: After a set cycle time, the concentrator automatically slows, allowing the concentrated goldbearing material to be flushed into a secure collection vessel for further processing or direct smelting.

Application scope includes processing hard rock mill discharge, alluvial placer material, and as a scavenger device for gravity recoverable gold (GRG) in cyanidation circuits. A key limitation is its dependence on the liberation size of the gold; it is most effective on free gold particles typically larger than 50 mesh.

3. CORE FEATURES

Enhanced GForce Bowl Design | Technical Basis: Computermodeled parabolic bowl geometry with deep, interlocking riffles | Operational Benefit: Creates a stable fluidized bed for superior separation efficiency, capturing ultrafine gold down to 50 microns | ROI Impact: Increases overall plant recovery by 38%, directly adding revenue from previously lost material.

Variable Frequency Drive (VFD) Control | Technical Basis: Precision electric motor control system | Operational Benefit: Operators can finetune rotational speed (and thus Gforce) in realtime to match changing feed conditions without stopping the process | ROI Impact: Optimizes performance across variable ore types, maximizing consistency and reducing process upsets that lead to grade loss.

Automated Discharge Cycle | Technical Basis: Programmable Logic Controller (PLC) with timerbased or sensoractivated cleaning cycles | Operational Benefit: Eliminates manual bowl cleaning, ensures consistent concentrate quality, and allows for unattended operation during shift changes | ROI Impact: Reduces labor requirements by an estimated 15 hours per week per unit and standardizes concentrate grade for downstream handling.

LowWash Water Requirement System | Technical Basis: Optimized internal water injection channels and pressure regulation | Operational Benefit: Achieves effective fluidization and concentrate rinsing with up to 40% less process water than previous generation models | ROI Impact: Lowers water pumping costs and reduces the volumetric load on water recycling systems or tailings dams.

Modular, CorrosionResistant Construction | Technical Basis: Bowl assemblies fabricated from highgrade polyurethane or ceramiclined steel; frames from powdercoated structural steel | Operational Benefit: Withstands abrasive slurries and harsh chemical environments, minimizing wear parts replacement frequency | ROI Impact: Extends mean time between failures (MTBF), cutting annual parts inventory costs by an estimated 20%.

Centralized Greasing Points & Access Panels | Technical Basis: Engineered maintenance accessibility based on field service feedback | Operational Benefit| Technicians can perform routine bearing maintenance and inspections in under 30 minutes without major disassembly| ROI Impact| Reduces planned maintenance downtime by over 50% per service event.

6. APPLICATION SCENARIOS

Hard Rock Gold Mine – Mill Scavenger Circuit | Challenge: A milling operation was losing significant gravityrecoverable gold (GRG) to its leaching circuit due to an inefficient primary concentrator, creating unnecessary cyanide consumption and processing cost.| Solution: Installation of two highG force centrifugal concentrators in parallel as a scavenger unit on the cyclone underflow stream.| Results: Field data shows a capture of an additional 1.5 grams of gold per tonne of ore fed to the leach circuit. This improved overall plant recovery by over two percentage points while reducing cyanide consumption by approximately eight percent within six months.

Alluvial/Placer Mining Operation – Primary Recovery Upgrade Challenge:| An alluvial operation using traditional sluices faced low recovery rates on fine gold particles (<150 mesh), especially during periods of high feed volume.| Solution:| Deployment of multiple mediumcapacity centrifugal concentrators configured as primary recovery units after initial screening.| Results:| Operators reported a quantifiable increase in total yield by over twentyfive percent compared to the previous season’s production figures from similar ground volumes processed through sluices alone.
