## 4. Working Principle
1. Feeding System: Raw ore is fed into the trommel for initial screening.
2. Washing & Scrubbing: Removes clay and debris.
3. Gravity Separation: Gold particles are concentrated using centrifugal force.
4. Final Refinement: Gold concentrate is further processed via sluice or mercury-free methods.
