While iron is a pivotal metal that is exploited commercially, its extraction from ores, subsequent processing and purification follows a series of steps, and material characterization in terms of physical, chemical and mineralogical features and behavior is imperative at each stage. Some characterization tests rely solely on physical measurements, while others are based on …
Electrochemical production of iron metal can support a decarbonized process for steelmaking. Here, we report a low-temperature, electrochemical cell that consumes low-cost and abundant iron oxide, salt, and water, while producing both iron and the alkaline electrolyte needed for efficient operation of the cell. Co-production of iron, lye, and chlorine leads to a process …
A method of direct reduction of iron (DRI) is disclosed, the method comprising generating metallic iron by removing oxygen from iron ore using a reducing gaseous mixture with excess carbon monoxide that produces an excess CO2 by-product is provided. CO2 by-product is optionally sequestered. A system for carrying out the method is also disclosed.
The papers selected range from an improved method for beneficiation of ultra-fine iron ore to granulation and sintering of iron ore and finally blast furnace performance and the …
Iron is currently produced by carbothermic reduction of oxide ores. This is a multiple-stage process that requires large-scale equipment and high capital investment, and produces large amounts of CO2. An alternative to carbothermic reduction is reduction using a hydrogen plasma, which comprises vibrationally excited molecular, atomic, and ionic states of hydrogen, all of …
While the deposit qualities for mineral raw materials are constantly decreasing, the challenges for sustainable raw material processing are increasing. This applies not only to the demand for minimizing the consumption of energy, water, and reagents, but also to the reduction of residual materials, especially fine and difficult-to-landfill materials. Sensor-based ore sorting …
