Harmony's Eva to Use ABB Drives

Why It Matters

Deploying ABB’s advanced drives gives Harmony Gold a competitive edge in a market where copper demand and energy costs are rising, while cementing ABB’s role as a technology supplier in Africa’s mining sector.

Key Takeaways

• Harmony Gold's Eva project valued at US$1.73 billion.
• ABB supplies 24 MW gearless and ring‑geared mill drives.
• Drives enhance energy efficiency and throughput for copper‑gold extraction.
• Partnership positions ABB as key player in African mining tech.
• Project aims to boost Harmony's copper output amid rising demand.

Pulse Analysis

Harmony Gold’s Eva project marks one of the most ambitious copper‑gold developments in Africa, with a capital outlay of roughly US$1.73 billion. The venture comes at a time when global copper consumption is projected to outpace supply, driven by renewable‑energy infrastructure and electric‑vehicle production. By integrating copper and gold extraction, Harmony aims to diversify revenue streams and mitigate commodity‑price volatility, positioning itself for long‑term growth in a resource‑rich region.

ABB’s selection of its 24 MW gearless mill drive (GMD) and ring‑geared mill drive (RMD) reflects a shift toward more efficient, high‑capacity grinding solutions. Gearless drives eliminate the need for traditional gearboxes, reducing mechanical losses and maintenance requirements, while ring‑geared drives offer robust torque handling for heavy‑duty milling. Together, these technologies can lower electricity consumption per tonne of ore processed, a critical advantage in South Africa’s power‑constrained environment. The equipment also supports higher throughput, enabling the Eva mine to reach its production targets faster than conventional setups.

The partnership signals broader trends in the mining industry: a push for energy‑saving equipment, increased automation, and a focus on sustainability. As African mines grapple with aging infrastructure and tightening ESG expectations, suppliers like ABB that deliver proven, low‑emission solutions are gaining strategic importance. For Harmony Gold, the ABB drives could translate into lower operating costs and a stronger ESG profile, while ABB strengthens its market share in a continent poised for a mining renaissance driven by the global transition to clean energy.
