Japan started the national project "COURSE 50" for CO2 reduction in the 2000s. This project aimed to establish novel technologies to reduce CO2 emissions with partially utilization of hydrogen in blast furnace-based ironmaking by 30% by around 2030 and use it for practical applications by 2050. The idea is that instead of coke, hydrogen …
It occurs in the iron ore mining benches either on the top of the ore or laterally with ore or within the ore, whose removal is imperative for proper development of mine benches during iron ore excavation. Based on the Fe%, as per IBM classification, Fe < 45% BHJ/BHQ has been classified as waste rock and more than 45% Fe as Sub-grade.
