Summary:Robert Friedland proposes replacing traditional SAG mill and ball mill circuits with I-ROX pulsed power technology, delivering up to 80% mining energy savings and higher mineral recovery for hard rock mining....
At the Mining Forum Americas in Colorado Springs, iconic mining investor Robert Friedland delivered a disruptive industry statement: the traditional SAG mill and ball mill grinding circuits that have dominated mineral processing for decades are set to be phased out. Instead, he advocates adopting I-Pulse’s revolutionary pulsed power mining technology, a game-changing solution that drastically cuts energy consumption and improves mineral recovery for global hard rock mining operations.
Robert Friedland keynote speech at Mining Forum Americas
Comminution (ore crushing and grinding) is widely recognized as the single largest energy-consuming process in the global mining industry. According to U.S. Department of Energy data, grinding operations account for 40% of total mining power consumption, placing enormous cost and carbon pressure on copper, gold, and critical mineral projects worldwide. Conventional SAG and ball mills rely on external compressive force, using steel media and gravity to grind ore, resulting in massive energy waste, high wear costs, and suboptimal metal recovery rates.
Friedland’s core innovation stems from I-Pulse’s proprietaryI-ROX pulsed power technology, a completely different ore fragmentation principle compared with traditional mechanical grinding. Instead of crushing rock from the outside, the system releases gigawatt-scale electrical pulses in microseconds, generating powerful internal shock waves that split ore along natural mineralogical boundaries. This inside-out crushing method fundamentally overturns decades of mining processing logic.
The technological advantages of pulsed power mining are unprecedented compared with traditional SAG mill circuits. The following table clearly outlines the performance gaps between the new-generation pulsed power solution and conventional grinding systems:
Processing Index | Traditional SAG & Ball Mill Circuit | I-ROX Pulsed Power Mining Technology |
|---|---|---|
Crushing Principle | External mechanical compressive force | Internal electric shock wave fragmentation |
Energy Consumption | Extremely high, 40% of mine total power use | Up to 80% energy reduction |
Metal Recovery Rate | Fixed, limited by mechanical grinding defects | Approx 5% recovery improvement |
Equipment Wear & OPEX | High liner and steel media replacement cost | Minimal mechanical wear, low operational cost |
Carbon Footprint | High power consumption leads to high emissions | Ultra-low carbon, eco-friendly processing |
Beyond energy savings and higher recovery, I-ROX pulsed power technology solves multiple pain points of modern mining operations. It produces fewer ultrafine ore particles during fragmentation, avoiding valuable mineral loss caused by over-grinding. For low-grade ore and marginal mineral deposits that are uneconomical for traditional SAG mill processing, this innovative technology can extend mine service life and unlock abundant idle mineral resources.
The technology has obtained strong industry recognition and capital support. Global top mining giants including Codelco, BHP, Rio Tinto and Newmont have completed strategic investments in I-Pulse. Ivanhoe Mines has conducted targeted ore testing at its Kamoa-Kakula copper complex, sending ore and tailings samples to I-Pulse’s professional R&D center in Toulouse, France, to verify industrial application feasibility. Supported by the US CHIPS Act’s $250 million funding, the technology is accelerating commercial iteration.
Not limited to ore crushing, I-Pulse’s unified pulsed power platform also empowers geothermal drilling via G-Pulse technology, achieving three times faster drilling speed and six times longer drill bit service life. The cross-scenario technical capability further proves the reliability and scalability of pulsed power energy application in the mining and energy industry.
Although the I-ROX technology is still in the large-scale test stage without fully published industrial operational data, its disruptive potential is reshaping the future of mineral processing. As global mining faces rising energy prices, carbon neutrality pressure and declining ore grade, the era of relying on SAG mills and ball mills for high-energy grinding is gradually coming to an end.
Robert Friedland’s bold statement at the Mining Forum marks a critical turning point for the global mining processing industry. The pulsed power mining technology developed by I-Pulse provides a revolutionary alternative to traditional SAG mill grinding circuits, bringing 80% energy saving, higher mineral recovery and lower carbon emissions. With continuous industrial verification and capital investment, this disruptive technology will become the core trend of low-carbon and efficient mining, completely rewriting the comminution rules of the global mining industry.
