Diffestages In Iron Ore Process

Combustion process. the iron in the processed ores must be dissolved out by chemical processes. this requires an element that binds oxygen more strongly than iron. this is exactly what carbon can do as a reducing agent.the carbon is fed to the blast furnace in the form of coke pyrolyzed coal from the coking plant.at sufficiently high temperatures the carbon can participate directly in the.
