Ferrous

Across the ferrous value chain—from iron ore mining to sintering, pelletising, and ferroalloy production—feed chemistry consistency is critical to operational performance and profitability.
Real-time online elemental analysers provide continuous measurement of key elements directly on conveyor belts, enabling immediate, data-driven control of ore classification, blending, and process feed preparation.

Key Operational Benefits

1. Accurate Ore Classification & Feed Control

Real-time measurement of Fe, SiO₂, Al₂O₃, CaO, MgO, Mn, and P allows.
  • Precise classification of ore by grade and impurity levels
  • Separation of high-value material from marginal or waste streams
  • Automated routing to stockpiles, plants, or export streams
Client Value:
Improved feed consistency into downstream processes and reduced variability-related losses.
Example Use Case:
High-grade iron ore is separated from lower-grade material in real time, ensuring only compliant feed reaches the blast furnace or export stream.

2. Optimised Blending for Process Stability

Consistent chemistry is essential for stable metallurgical performance.
Real-time data allows:
  • Blending from multiple sources to meet target specifications
  • Control of gangue elements for optimal slag chemistry
  • Stable process conditions across shifting ore sources
Client Value:
Reduced process variability, improved throughput, and consistent product quality.
Example Use Case:
Scanmin FNDAA measures Organic and in Organic elements directly, allowing simultaneous measurement of flux, reductant and concentrate
Sinter plant blending is dynamically adjusted to maintain target basicity, improving sinter strength and permeability.

3. Improved Energy Efficiency & Cost Reduction

Feed composition directly impacts energy consumption and reduction efficiency.
Real-time analysers support:
  • Avoidance of high-gangue, energy-intensive feed
  • Stable burden composition for predictable thermal behaviour
  • Optimised reductant and flux consumption
Client Value:
Lower power, fuel, and reductant costs per tonne produced.
Example Use Case:
Pellet plant operators reduce fuel consumption by controlling silica and alumina levels in real time.

4. Enhanced Product Quality & Reduced Penalties

Upstream control protects downstream specifications.
Real-time measurement enables:
  • Early detection and diversion of off-spec material
  • Consistent adherence to customer and market requirements
  • Reduced risk of penalties, downgrades, or rejected shipments
Client Value:
Improved revenue assurance and stronger customer confidence.
Example Use Case:
Phosphorus levels are continuously monitored to prevent off-spec export shipments.

5. Faster Decisions, Reduced Sampling Dependence

Traditional lab sampling introduces delays that limit responsiveness.
Online analysers provide:
  • Continuous, real-time elemental data
  • Immediate detection of feed changes
  • Faster operational decision-making
Client Value:
Proactive control instead of reactive correction.
Example Use Case:
Operators adjust blending ratios instantly on a conveyor feeding a DRI plant, avoiding hours of delay from lab results.

6. Improved Mass Balance & Resource Utilisation

Accurate grade data enables:
  • Reliable metal accounting and reconciliation
  • Improved recovery through controlled feed quality
  • Effective use of marginal ores via blending
Client Value:
Higher yield, better resource efficiency, and improved life-of-mine economics.
Example Use Case:
Mine-to-port reconciliation is improved through continuous tracking of grade and tonnage.

7. Reduced Operational Risk & Environmental Impact

Consistent feed preparation delivers broader benefits.
  • Fewer process upsets and unplanned shutdowns
  • Lower slag volumes and waste generation
  • Reduced rehandling and reprocessing
  • Improved environmental compliance
Client Value:
Safer, more stable operations with reduced environmental footprint.
Example Use Case:
Stable feed chemistry reduces slag variability in ferroalloy furnaces, improving operational reliability.
