Targeting HighYield, LowCost Gold Recovery: The Advanced Centrifugal Concentrator Solution

1. PAINPOINT DRIVEN OPENING

Maximizing gold recovery from alluvial and hard rock deposits is a constant pressure. Are you facing these specific operational challenges?
Fine Gold Loss: An estimated 1530% of micron and fine gold (<100 mesh) is lost to tailings in traditional sluice and jig operations, representing direct revenue leakage.
High Operational Labor & Water Consumption: Constant manual cleanups, monitoring, and highvolume water recirculation systems drive up operational costs and environmental management complexity.
Inefficiency with Variable Feed Grades: Conventional equipment often has a narrow optimal feed grade range, leading to poor performance during grade fluctuations and requiring frequent adjustment.
Downtime for Concentrate Cleanup: Production halts for routine concentrate retrieval directly impact total processing volume and equipment utilization rates.

How can your operation capture a higher percentage of free gold, especially fines, while reducing pertonne processing costs and operator dependency? The solution lies in precision gravity separation.

2. PRODUCT OVERVIEW: Advanced Centrifugal Concentrator

The Falcon C Series Enhanced Gravity Concentrator is a continuousbatch centrifugal concentrator designed for the highvolume recovery of free gold, particularly micron and fine gold particles. It enhances gravitational force to separate highdensity minerals from gangue.

Operational Workflow:
1. Slurry Introduction: A controlled density slurry feed is introduced into the rotating bowl.
2. Centrifugal Concentration: Under intense centrifugal force (up to 300 G's), dense gold particles are forced against the bowl's concentrating grooves, while lighter material fluidizes and is expelled.
3. Automatic Concentrate Retention: Gold is trapped and retained within the bowl throughout the batch cycle.
4. Automated Purge Cycle: At a preset interval, the rotation slows, and an automated water purge cleans the concentrated gold into a secure collection vessel, with minimal operator intervention.
5. Continuous Operation: The unit resumes feed intake immediately after purging, enabling nearcontinuous processing.

Application Scope: Ideal for freemilling alluvial (placer) operations, hard rock mill grinding circuits (as a gravity recovery device), and scavenging applications from existing tailings streams.
Limitations: Not suitable for chemically bound (refractory) gold or ores where gold is locked within sulfide matrices without prior liberation. Performance is dependent on proper particle size liberation and feed slurry density control.
