(2)hot air blast in (3)co2 and waste gases removed 6 of 13 bottom of blast furnace molten **** (****s on top!) molten iron - bottom 7 of 13 blast furnace word equation carbon+oxygen>carbon dioxide 8 of 13 blast furnace symbol equation C(s)+O2(g)>CO2(g) 9 of 13 carbon MONoxide 2CO 10 of 13 aluminium properties strong, low density, thermal conductor, non-magnetic, resistant to corrosion electrical conductor, moluable 11 of 13 smelting roasting 12 of 13 crude unpure 13 of 13
