Meiteng’s ZhiMei Master large AI model for coal preparation was showcased at a CCPUA technical exchange in Jincheng on 24–25 April 2026, hosted with Jinneng Holding Equipment Manufacturing Group. Built on domain data from dense medium separation, flotation and dewatering circuits, the model targets intelligent control of product ash, yield and reagent dosage across complex coal washing plants. For process engineers, the move signals rapid deployment of plant-level AI optimisation in China’s large state-owned coal operations, with implications for retrofitting existing preparation facilities.

XCMG all‑electric heavy‑duty trucks have completed trial runs on the 700 km haul route between Codelco’s Chuquicamata copper mine and the port of Mejillones in northern Chile with zero reported malfunctions. The route, crossing the western Andean foothills, tests traction, braking and battery performance under high-altitude gradients, long downhill sections and desert temperatures. Successful operation over this distance signals growing feasibility of battery-electric haulage for mine‑to‑port logistics, with implications for charging infrastructure design, duty‑cycle planning and fleet energy management.

GR Engineering Services has been named preferred EPC contractor by Ora Banda Mining to deliver a 3 Mt/y gold process plant for the Davyhurst Expansion Project in Western Australia. The appointment follows Ora Banda’s ASX update outlining a step-up from the current 1.2 Mt/y Davyhurst plant, signalling a major throughput increase across its existing open pits and underground resources. For plant designers and contractors, the project points to upcoming demand for larger comminution, leach and tailings handling circuits in the Eastern Goldfields.
