The blast furnace and direct reduction processes have been the major iron production routes for various iron ores (i.e. goethite, hematite, magnetite, maghemite, siderite, etc.) in the past few decades, but the challenges of maintaining the iron and steel-making processes are enormous. The challenges, such as cumbersome production routes, scarcity of …
