How China's unwritten rules are squeezing global

Aug 17, 2021Higher-purity iron ores generate less slag when consumed in blast furnaces, allowing coke rates to be kept lower, while direct-charge ores such as lump and pellet also lessen the consumption of coke breeze in the sintering process. Using higher-grade iron ore feedstocks is therefore preferable for mills when coking coal prices are high.
