    Talk:Iron ore - Wikipedia

    The article states "With the chemical formula Fe3O4, magnetite ore has much lower iron content than hematite ore" (Fe2O3). Based on the formula, my maths has magnetite having the higher percentage of iron vs oxygen, and indeed this is what is stated in the introduction also. My guess is this sentence is supposed to mean something other than what is written, but I'm not sure what that might be ...
