Market Developments and Procurement Priorities
Mining wear-part procurement should consider mineral demand and equipment utilization alongside supply-chain conditions and maintenance plans. Electrification and energy technologies support critical mineral demand, but mineral demand projections do not directly establish wear-part market values or service-life guarantees.
Key Demand Considerations for 2026
1. Critical Mineral Demand
Lithium, copper, nickel and rare-earth projects differ in ore characteristics and process routes. Assess wear-part requirements for the specific equipment and duty:
- Hard-Rock Lithium: in spodumene processing, abrasion depends on mineralogy, particle characteristics and loading. Low-impact wear locations may be assessed for High-Chromium Cast Iron and ceramic composite designs validated for the application.
- Porphyry Copper: continuous processing requires coordinated liner replacement, lifting arrangements and shutdown windows.
- Lateritic Nickel: sticky ore with a high fines or clay content requires attention to handling conditions and associated wear.
Base procurement plans on the mine production schedule, ore changes, historical consumption and maintenance intervals.
2. Expansion and Upgrades at Existing Mines
Expansion or increased output at an existing mine can change feed conditions, loading and maintenance schedules. Reassess liner configurations, critical part lead times and inventory instead of carrying forward earlier consumption assumptions.
3. Automation and Predictive Maintenance
Wear measurements and equipment condition monitoring can support maintenance and procurement planning. Define the measured variables, data quality, installation requirements and maintenance decision process when selecting a monitoring system.
Technology Developments to Assess
| Technology | Assessment Stage and Conditions | Implications for Wear Parts |
|---|---|---|
| Ceramic and Carbide Composites | Assess for the specific part | Assess the wear layer, supporting structure and impact limits without assuming a universal service-life multiplier. |
| Bimetallic Castings (Cr+Mn) | Depends on structure and interface design | Review bonding, residual stress and failure modes. |
| Sand Moulds Made by 3D Printing | Select for the casting and process | Can support complex mould cavities; lead times must include casting, heat treatment, machining and inspection. |
| AI-Based Wear Prediction | Validate with site data | Continuously check predictions against measured wear and maintenance records. |
| Surface Nanostructuring | Assess the specific process | Assess surface properties, toughness and stability in service together. |
Ceramic and carbide composites require assessment for the installation position. Compare downtime, replacement, scrap and cost per unit processed alongside purchase price. High-impact SAG applications particularly require structural and fracture-risk assessment.
Supply-Chain Considerations
- Supplier Manufacturing Capability: assess foundry processes, inspection, traceability and batch consistency. Evaluate Manganese Steel and high-chromium white iron suppliers against the same technical specification and acceptance conditions.
- Delivery and Regional Inventory: plan regional inventory around transport time, customs clearance, demand variability and shutdown risk.
- Supply Routes and Alternatives: separately confirm OEM and independent supplier quotation scope, specifications, lead times and responsibilities. Brand or location alone does not establish supply capability.
Procurement Recommendations
- Diversify Qualified Supply Sources—qualify suppliers and alternative sourcing routes according to part criticality.
- Evaluate Material Improvements—compare materials and designs through site trials, and evaluate returns using measured wear and replacement costs.
- Plan Critical Inventory—set inventory levels from consumption variability, replenishment lead time and downtime consequences rather than a fixed number of days.
- Use Condition Data in Procurement—link wear-monitoring data with purchasing systems.
- Agree on Total Cost Measures—consider cost per tonne processed alongside price per kilogram.
Outlook
In 2026, wear-part procurement should combine materials knowledge, site data and supply-risk management. Link material trials, quality records and maintenance feedback to improve purchasing decisions.
