China begins mining iron from tailings, low-grade ore that can meet its demand for decades

Scientists have found a way to turn waste into a valuable resource on an industrial scale, reducing China’s dependence on iron ore imports According to the Chinese Academy of Sciences (CAS) last Tuesday, a production line capable of processing 5.56 million tonnes of refractory iron ore and tailings per year has passed official checks and is now running steadily. On the other hand, China has the fourth-largest iron ore reserves, yet most are low grade, and nearly half are too hard and costly to process with standard methods. So huge amounts remain unused. The new breakthrough aims to make those hard-to-use ores viable. State broadcaster CCTV reported that the technology could fundamentally strengthen China’s ability to secure its own iron resources and reduce its heavy dependence on imports of the strategic commodity.
