Solving the Clay Crisis: High-Impact Gold Ore Washing in West Africa

How HSM’s rotary washing technology restored production flow for a top-tier gold mining operation.

Operational Bottleneck

A prominent mining site in Ghana struggled with extreme clay contamination within their quartz-hosted gold deposits. During the rainy season, the sticky matrix would encapsulate the ore, leading to catastrophic clogging of secondary crushers and rendering traditional screens useless. This inefficiency led to a persistent 20% deficit in target throughput and frequent, costly maintenance interventions.

The HSM Engineering Response

HSM deployed a site-specific GTS1550 Industrial Washing Trommel. Unlike standard dry screens, this unit was outfitted with a comprehensive material scrubbing package:

  • Integrated Scrubber Spray System: A dual-line high-pressure water manifold was mounted inside the drum, delivering a constant abrasive wash that stripped clay from the quartz surface during rotation.
  • Tough-Mesh Polyurethane Media: We replaced standard steel with high-impact PU panels, which provide natural elasticity to shed sticky fines and offer 3x the wear life in abrasive gold environments.

Performance Benchmarks

Stable Throughput: Maintained a reliable 150 m³/h flow rate regardless of weather.
Clay Rejection: Achieved near-total removal of slimes prior to the crushing stage.
Crusher Protection: Extended liner life by 35% by eliminating “packing” in the crusher cavity.

Eliminate Clogging in Your Process
