Targeting Plant Managers & Procurement Directors: Solving HighCost, LowYield Recovery in Hard Rock Gold Operations

Are your gold recovery rates plateauing despite increasing energy and reagent costs? Is unscheduled downtime for maintenance on your primary concentration equipment eroding your profit margins? You face the constant pressure to improve yield from complex, lowergrade ores while controlling operational expenses. How do you increase throughput without compromising recovery efficiency? Can your current setup handle variable feed grades without manual intervention and significant yield loss? The solution requires equipment engineered not just for capacity, but for intelligent, reliable performance in demanding conditions.

Product Overview: Premium HighGrade Gold Concentrators

The {{keyword}} is an advanced centrifugal concentrator designed for the continuous recovery of free gold, sulphideassociated gold, and other heavy minerals from grinding circuit discharges or as a primary rougher/scavenger device. Its operational workflow is based on a enhanced gravitational separation process: 1) Feed Introduction: Slurry is introduced into a rapidly spinning rotor. 2) Acceleration & Stratification: Centrifugal force (typically 50200 G's) forces particles against the concentrating wall, creating a stratified bed where heaviest particles migrate inward. 3) Fluidized Bed Separation: A controlled fluidization water system maintains particle mobility, allowing heavy minerals to be trapped while lighter gangue is flushed away. 4) Continuous Concentrate Extraction: A patented rinse cycle or continuous extraction system removes the enriched concentrate with minimal interruption to processing. 5) Tailings Discharge: Depleted slurry exits as tails.

Application Scope: Ideal for recovering free gold >30 microns, sulphide concentrates, and platinum group metals from hard rock operations. Limitations: Less effective on ultrafine (<10 micron) gold without preclassification; requires consistent feed density and pressure control for optimal performance.

Application Scenarios

HighGrade Vein Mining with Variable Ore

Challenge: A midtier producer faced erratic recovery rates (8594%) due to highly variable feed grade from selective mining, leading to significant gold loss in scavenger circuits during highgrade surges.
Solution: Installation of two {{keyword}} units as primary roughers with automated controls tied to upstream grade monitoring.
Results: Recovery stabilized at a minimum of 96.5%, capturing "surge" gold previously lost. Annualized yield increased by an estimated 420 ounces in the first year.

Refractory Sulphide Operation PreConcentration

Challenge: Before oxidative processing, a plant needed to create a highermass pull sulphide concentrate without excessive dilution or use of reagents.
Solution: Implementing a {{keyword}} circuit after regrind mills to create a bulk sulphidegold concentrate.
Results: Produced a consistent concentrate representing 12% of feed mass while capturing >92% of sulphidebound gold. This reduced downstream tank oxidation costs by approximately $11/ton of concentrate treated.

Frequently Asked Questions

1. Is the {{keyword}} compatible with our existing cyclone underflow or mill discharge setup?
Yes. The unit is designed as a dropin solution for standard grinding circuit configurations. Our engineering team provides a full interface review to ensure proper pump sizing and piping integration.

2. What is the typical installation and commissioning timeline?
For a standard unit with prepared foundations, mechanical installation requires 35 days. Commissioning and performance tuning typically takes an additional 23 days of continuous operation with your ore.

3. How does the automation system respond to sudden changes in feed grade or volume?
The PLC can be programmed with multiple setpoints for fluidization water and Gforce via the VFD. It can accept an analog signal from an upstream density meter or flow transmitter to automatically adjust parameters within predefined limits.

4. What are the ongoing operational consumables?
Primary consumables are liner segments (life varies from .00–12 months based on abrasiveness), occasional valve diaphragms, and standard greases for bearings. The system does not require specialized chemicals or reagents.

5. Can you provide performance guarantees?
Yes, we offer conditional recovery guarantees based on a representative metallurgical test of your ore conducted at our facility or an agreedupon thirdparty lab prior to purchase.
