- Documented references: gold, silver, and high-quartz gangue
Maximum performance
High-chromium cast grinding ball
Designed for high-tonnage, high-abrasion operations. It offers maximum wear resistance, lower g/t consumption and less iron contamination. Ideal for gold and silver extraction, and for operations that need an all-terrain ball with superior performance.
Key benefits
- Maximum resistanceExcellent performance under severe abrasion.
- Lower consumptionReduces media consumption per processed tonne.
- Less contaminationBrings cleanliness and stability to the process.
- All-terrain ballCan be used in any active process at the mine.
