The number of reducing agents involved in the extraction of iron (as pig iron) using blast furnace from ore haematite is

Answer»


Solution : At 500-800 K (lower TEMPERATURERANGE in the blast furnance)
`3Fe_(2)O_(3) + CO to 2Fe_(3)O_(4)+CO_(2)`
`Fe_(2)O_(4) + CO to 3Fe_(3)+4CO_(2)`
`Fe_(2)O_(3) + CO to 2FeO+CO_(2)`
At 900-1500K ( HIGHER temperature range in the blast funcance)
`CF+CO_(2) to 2CO. FeO+CO to Fe +CO_(2)`
