Mineral Technologies has launched mtOne, a real-time automation platform for spiral gravity separators that it positions as a complete re‑design of spiral operation from 2026 onwards. The system is aimed at replacing manual “walk‑by” inspection and adjustment of spiral banks with continuous monitoring and automated control of operating parameters. For plant metallurgists and process control teams, this signals a shift towards closed-loop optimisation of spiral circuits, with potential impacts on staffing patterns, sampling strategies and integration with existing SCADA/DCS infrastructure.

Martin Engineering will use CONEXPO-CON/AGG 2026 in Las Vegas (3–7 March) to unveil new heavy-duty belt conveyor accessories developed at its Center for Innovation (CFI). The line-up will include upgraded belt sealing systems and bulk material flow technology aimed at reducing spillage and improving transfer-point performance on high-capacity conveyors. For mine operators, the focus is likely to be on retrofit-friendly designs that cut maintenance time and improve belt life on existing overland and plant conveyor circuits.

New iron ore pricing arrangements being trialled between Chinese steel mills and major Australian producers such as Rio Tinto have prompted the Australian Government to step up monitoring of contract structures and benchmark references. Officials are scrutinising shifts away from traditional Platts index-linked, 62% Fe fines contracts towards more flexible, possibly shorter-tenor or blended-grade pricing formulas negotiated directly with Chinese buyers. Any move in large-volume offtake contracts could alter realised prices at Pilbara operations, affect mine planning and grade control strategies, and influence long-term investment assumptions for new iron ore capacity.
