ABB will provide gearless and ring-geared mill drives for the semi-autogenous grinding and ball mills at Harmony Gold’s proposed US$1.75 billion Eva copper project in Queensland, Australia, to help “drive system efficiency” in a circa- 18 million tonnes per annum processing plant.
Harmony last year approved $1.55-1.75 billion of capital spend for Eva, where it aims to start production in 2028. The large openpit copper-gold project is expected to produce an average 60,000tpa copper and 19,000ozpa gold over a 15-year mine life, at $2.49/lb copper AISC for the first five years.
Eva’s 24MW SAG and 18MW ball mills will be the biggest power users on site. ABB said its gearless SAG mill drive and variable-speed ring-geared ball mill drive
“ABB’s technology will enable grinding with maximum efficiency, reliability and operational flexibility, suitable for a modern concentrator designed around contemporary processing flowsheets and low-risk technology choices,” ABB said.
It said the Eva sale was booked into its 2025 Q4 orders but didn’t disclose its value.
