Gold Ore Pre-Washing: Maximizing Beneficiation Efficiency in West Africa
How HSM’s wash-integrated trommel technology eliminated clay-clogging for a major mining client.
1. The Challenge
A gold mining operation in Ghana faced a severe operational bottleneck due to high clay content in their raw ore. The sticky clay adhered to the quartz, clogging downstream crushers and blinding traditional vibrating screens. This resulted in frequent emergency shutdowns and a 20% drop in overall processing efficiency, significantly impacting the mine’s daily yield.
2. HSM Solution
To address these specific geological conditions, HSM engineered a customized GTS1550 Wash-Integrated Trommel Screen. Key design features included:
- Heavy-Duty Internal Spray Bars: Strategic placement of high-pressure nozzles provided continuous scrubbing as the ore tumbled, stripping away stubborn clay.
- Modular Polyurethane (PU) Panels: Selected for extreme wear resistance and superior desliming performance, ensuring the mesh remained clear even during the rainy season.
3. The Proven Result
| Throughput: | Achieved a consistent 150 m³/h capacity. |
| Cleaning Efficiency: | Successfully removed 98% of adhering clay and slimes. |
| Maintenance ROI: | Downtime reduced by 40%, extending the service life of secondary crushers. |
