ABB has secured a contract to supply both gearless mill drive (GMD) and ring-geared mill drive (RMD) systems for Harmony Gold’s Eva Copper Mine Project, a new open-pit operation about 75 km north of Cloncurry in northwest Queensland. The package will cover large SAG and ball mill installations, combining high-torque GMDs with RMDs for smaller mills to optimise grinding circuit flexibility and electrical efficiency. For process and electrical engineers, the choice of mixed GMD/RMD architecture signals a focus on variable-speed control, reduced mechanical components and lower maintenance in a greenfield copper concentrator.

R-evolution, Hexagon’s green-tech subsidiary, has begun its first missions using hybrid airborne imagery and LiDAR over a Vale legacy mine site as part of the Hexagon Green Cubes digital twin programme. The system fuses high-resolution optical data with LiDAR-derived elevation models to capture complex topography, waste dumps and water bodies in a single georeferenced dataset. For mine closure and reclamation teams, this enables more accurate volumetrics, subsidence detection and slope stability assessment than conventional photogrammetry alone.

ABB has signed an agreement with Harmony Gold to supply power and automation solutions for the Eva Copper project in Queensland, targeting higher plant efficiency as copper demand rises. The deal is expected to cover integrated electrification and process control systems for the greenfield operation, enabling coordinated management of crushers, mills and material handling. For engineers, the move signals continued investment in high-availability electrical infrastructure and digital control at large-scale Australian copper projects as they move from design to execution.
