The use of concentrated solar energy to weaken rocks and reduce their grinding energy

This study used a high-flux solar simulator to induce thermal shock in gold ore (600–800°C, 2.5–7.5 min) as a zero-carbon alternative to furnace-based pretreatment. By analyzing mass loss, XRD/XRF mineralogy, BET surface area, and the Bond Work Index, it shows that solar-driven thermal shock creates internal microcracking that cuts grinding energy by up to ~70% (from 558 to 167 kWh/ton at 800°C), matching the benefits of conventional furnace thermal shock while replacing grid electricity with concentrated sunlight.
