China makes new progress in flash ironmaking technology

China has achieved breakthroughs in flash ironmaking technology, a process capable of boosting ironmaking efficiency by up to 3,600 times, according to a recent study published by a researcher of the Chinese Academy of Engineering (CAE) in Nonferrous Metals (a leading technical journal in the nonferrous metals industry in China).

Flash smelting involves injecting metal concentrates and reducing gases such as hydrogen or natural gas into a furnace, where the wide dispersion of concs creates optimal conditions for chemical reactions, enabling the rapid production of high-purity metals, according to the study paper. This method has been widely used in
