Aspect ratio is one of the most critical design parameters in rotary drum scrubbers, directly affecting residence time, scrubbing intensity, and circuit performance. From fast throughput in low L/D drums to deep-cleaning in high L/D designs, choosing the right geometry can determine whether your plant operates efficiently or struggles with sticky ores.

Unlocking Gold: Why Ore Type Matters Every gold deposit tells a different geological story—and getting that story right is key to maximizing recovery and minimizing cost. From simple oxide ores to complex refractory bodies, understanding your ore type is the foundation of efficient, profitable gold processing.
