Why high-grade iron ore is set to outperform other
2021-3-25 Higher-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.

Iron Ore Recovery from Low Grade by using Advance
2015-1-1 The main difficulty in processing and utilization of low-grade iron ores primarily stems from their mineralogical characteristics as well as the soft nature of some ores and their high silica content. Thus, beneficiating the low-grade iron ores to remove the gangue minerals and enhancing their grade is an attractive proposition today.
