Project Background:

A mineral processing plant in Australia aimed to enhance the comprehensive recovery rate of coastal sand minerals (including ilmenite, zircon, and rutile) by adopting an environmentally friendly beneficiation process.

Solution:

We designed a specialized coastal sand processing line for the client. This line consists of a Trommel Screen, Spiral Chute, Shaking Table, Magnetic Separator, and High-Tension Electrostatic Separator. The trommel screen efficiently removes oversized materials, while the spiral chute pre-concentrates heavy minerals using gravity and centrifugal forces. The shaking table further refines the concentrate. The dry magnetic separator extracts magnetic minerals like ilmenite, and finally, the High-Tension Electrostatic Separator separates non-magnetic minerals. The entire physical separation process avoids chemical usage, ensuring zero pollutant emissions and minimizing environmental impact.

Key Results:

Overall mineral recovery rate increased by 20% through the multi-stage gravity separation process.

Daily processing capacity increased by 43%, and operational costs reduced by 15%.

Zero pollutant discharge during the process, leading to a 95% reduction in environmental costs.
