In this lesson, we are going to discuss the environmental effects of extracting iron from blast furnace.
(i)Carbon (IV) oxide gas given out causes/ increases global warming if allowed to escape/leak from the furnace.
(ii)Carbon(II)oxide gas is a highly
poisonous/toxic odourless gas that can kill on leakage. It is preferentially absorbed by the haemoglobin in mammals instead of Oxygen to form a stable compound that reduce free haemoglobin in the blood.
(iii) Haematite (#Fe_2O_3#), Magnetite(#Fe_2O_4#) and Siderite (#FeCO_3#) are extracted through open cast mining that cause soil / environmental degradation.
