... ore contains >50 % Fe. These high concentrations make it relatively easy to extract the metals and this, combined with the relative abundance of these deposits, is reflected in their low metal prices, only $1.5 per kg for Al and less than $0.1 per kg for Fe. Iron alone accounts for over a quarter...
