Iron Ore Quality 9 The average quality of iron ore has been in decline for years. Formerly, the average Fe% was above 62% with 5% impurities (gangue) but by 2016 the respective figures were 61% and 6.5% for the big four mining companies. Excessive gangue not only needs more electric power in the EAF but lowers the melting yield,
