What it is
A high-grade, precision-graded limestone flux formulated for iron ore sintering operations — where consistent CaO delivery, controlled basicity, and optimised particle gradation are the defining variables in sinter bed structure, mechanical strength, and blast furnace reducibility.
What it does
- Stabilises CaO input across sinter batches for consistent basicity control
- Improves sinter bonding, mechanical strength, and bed permeability
- Enhances blast furnace reducibility through optimised sinter formation
- Reduces return fines and process losses across high-throughput sintering cycles
- Supports uniform, continuous sintering operation with predictable thermal behaviour
- Regulates slag fluidity and impurity separation in integrated steelmaking operations
Where it’s typically used
Sinter plants in integrated steelmaking operations where basicity control, sinter bed permeability, and mechanical strength are process-critical — and as a flux input in metallurgical operations requiring consistent, high-grade CaO delivery across continuous production cycles.

What makes SinterPure the preferred flux for iron ore sintering operations?
SinterPure delivers controlled CaO content of 52 – 54% with precision particle gradation — ensuring consistent basicity, optimised bed permeability, and superior sinter mechanical strength that directly improves blast furnace reducibility and campaign stability.
How does SinterPure reduce process losses in high-throughput sinter plants?
Its controlled top-cut sizing and optimised particle size distribution minimise return fines generation — sustaining uniform sinter bed formation, reducing rework, and supporting continuous high-throughput sintering with predictable thermal behaviour.
Can SinterPure support slag control beyond the sinter plant?
Yes. SinterPure's high-grade CaO content and low impurity profile extend its value into integrated steelmaking — regulating slag fluidity, supporting phosphorus and sulphur removal, and protecting refractory lining integrity across BF and BOF operations.
