They were made by...Processes that produce iron by reduction of iron ore (in solid state) below the melting point are generally classified as DR processes. Based on the types of reductant used,

the only emissions from the process is water and pure iron pellets. The production process is centered around a 5-ton Bell furnace with electric heating units. The furnace is charged with oxidized iron-based pellets and evacuated. Thereafter the furnace is heated to ca 650°C and pressurized hydrogen is added.网页The blast furnace uses coke,

since the blast furnace is much the most efficient process coking coal the only emissions from the process is water and pure iron pellets. The production process is centered around a 5-ton Bell furnace with electric heating units. The furnace is charged with oxidized iron-based pellets and evacuated.
