Technology-led optimisation of comminution circuits can deliver immediate, material efficiency gains when applied with tight process control, argues JD Singleton, Comminution Director for EMEA at Weir. Singleton links precision deployment of tools such as high-pressure grinding rolls, advanced process control and real-time ore characterisation to lower specific energy consumption and reduced CO₂ per tonne milled. He stresses that disciplined implementation and continuous performance tracking are essential if mines are to meet carbon targets without escalating unit operating costs.

Darma Henwa has expanded its fleet with 10 new Liebherr machines to support increased overburden and coal production at Kaltim Prima Coal’s Bengalon mine in East Kalimantan and Arutmin’s Kintap mine in South Kalimantan. The additional units, likely including large hydraulic excavators and ultra-class mining trucks typical of Liebherr’s Indonesian deployments, are being deployed to a new pit at Bengalon and to meet higher production targets at Kintap. For mine planners and geotechnical teams, the larger fleet implies higher stripping rates, faster pit advance and tighter haul road and dump stability requirements.

Eldorado Gold has produced first copper-gold concentrate from its wholly owned Skouries project in northern Greece, signalling the shift from construction to operational ramp-up at this long-delayed porphyry deposit. The company is targeting commercial production in the December quarter of 2026, with Skouries designed as a combined open-pit and underground operation using conventional crushing, grinding and flotation to generate a high-grade copper-gold concentrate. Early plant performance and de-bottlenecking over the next two years will be critical for validating throughput, recovery assumptions and tailings management strategies.
