Less Energy Required.

Direct RF Heat.

Designed to deliver energy directly into materials to reduce heat losses, lower energy intensity, and improve recovery across mining and mineral processing.

Energy-Efficient Electrification for Critical Minerals Processing

At Acceleware, we apply advanced radio frequency (RF) heating to deliver energy directly into materials, reducing the energy required to achieve industrial process heat. Powered by our proprietary Clean Tech Inverter (CTI), RF Direct Heat enables highly efficient electrification of energy-intensive thermal applications in mining and minimizes heat transfer losses common to conventional systems.

Originally developed to electrify heavy oil production, the CTI has evolved into a cross-sector industrial heating platform. The same electromagnetic heating technology demonstrated (TRL 9) through a C$30M industrial pilot is now being applied to mineral processing, where it has the potential to lower energy intensity, improve throughput or yield, and reduce emissions.

Core Benefits

50–75% lower energy intensity potential

RF energy is coupled directly into the material being heated, reducing losses associated with heating air, steel, and surrounding infrastructure.

Potential improved recovery and production

Faster leach kinetics, uniform drying, better process control

Improved process performance

Uniform heating improves moisture control, material flowability, and process stability, supporting higher throughput and more consistent downstream operations.

Scalable electrification

RF Direct Heat enables practical electrification of mine-scale thermal processes, reducing reliance on combustion and improving compatibility with renewable power sources.

How RF Direct Heat Works

Acceleware converts electricity into RF energy and delivers it directly into the material, enabling volumetric heating, selective coupling (e.g., to water), and elimination of surface and convective heat-transfer losses.

RF Direct Heat for Copper, Gold & Nickel Recovery

Temperature is the single most important lever on heap leach performance. RF Direct Heat could deliver energy-efficient, mine-scale heat to improve recovery across copper, gold, and nickel operations, without combustion or additional process water.

The Opportunity

200+ active heap leach operations worldwide

~20% of global copper supply comes from leaching

70% of earth's copper is locked in chalcopyrite, mine-scale RF heat unlocks it

Production Impact

Recent Mining Developments:

Feasibility Studies with BHP

In 2025, Acceleware partnered with BHP on paid feasibility studies evaluating RF heating in mineral processing applications, including:

Iron ore drying (Australia): Evaluation of RF heating to efficiently reduce moisture content to improve flowability, a key constraint on processing throughput.

Copper heap leach heating (Chile): Assessment of RF-based thermal enhancement to improve copper recovery while minimizing energy required for heap heating.

These studies are validating EM Powered Heat’s potential to expand into diverse mining environments and use cases.

Advancing Potash Drying and Industry Collaboration

Building on collaboration with the International Minerals Innovation Institute (IMII), Acceleware is advancing the next phase of our TRL 6-7 CTI-powered potash ore and fines drying project in Canada. This work is supported by IMII members BHP, Nutrien, and The Mosaic Co., and aims to scale RF drying technology and demonstrate reductions in energy required, operating costs, and emissions reductions potential compared with conventional thermal drying methods.

Acceleware’s partnership-led development approach reflects a commitment to practical, scalable solutions for critical minerals processing.
