China’s breakthrough transforms iron production efficiency

China has developed a revolutionary ironmaking technology called flash ironmaking, which completes the process in just three to six seconds. It works by injecting finely ground iron ore into a superheated furnace, triggering an explosive chemical reaction that creates glowing iron droplets. These droplets collect at the furnace’s bottom, producing high-purity iron. This method streamlines production by eliminating multiple stages, allowing for more efficient casting or direct steelmaking.
