CALCULATIONS
Calculation of Fe203 in Hematite:
Step 1:

Step 3:
Step 4:
Step 5:
Step 6 :
=
=
=
mole Fe mole FeO %FeO I (56 + 16) 86 .60 I (56 +16)
4 mole Fe reacts with 3 mole 02 resulting in 2 mole Fe203
therefore , mole Fe203 = 0.5x mole Fe
mole Fe203 = 0.5 x 1.20 = 0.6
% Fe203 mole Fe203 x 160 0 .6 x 160 96
Recalculate to give resu lts of Hematite in Table B

Recalculation of Fe203 and FeO in Magnetite assuming a M304 structure
Step 1:
Calculate th e mole cations from the chemical analyses shown in TAB LE A
Step 2:
Recalculate the mole cations to ensure that the sum of the cations equals 3
Step 3:
Determine the mole oxygen anions associated with the cations as calculated in step 2
Step 4:
Fe3+ cations is present if the total mole oxygen anions calculated in step 3 is less than four.
Step 5:
mole Fe3+ cations = 2 x (4 - total mole oxygen anions) = 2 x (4 - 3.02) = 1.96
Step 6:
%Fe203 = (mole Fe3+ cations x total mole cations / 3) x 160 x 0.5
therefore, %Fe203 = 1.96 x 1.33 / 3 x 160 x 0.5 = 69 .51
Step 7:
mole Fe2+ cations = mole Fe2+ cations calculated in step 3 - mole Fe3+ cations = 2.63 - 1.96 = 0.67
Step 8:
%FeO = (mole Fe2+ cations x total mole cations / 3) x 72
therefore, %FeO = 0.67 x 1.33/3 x 72 = 21.39
Step 9:
Recalculate to give results of the chemical analyses of Magnetite in Table B
Step 10:
Accordingly , Magnetite Stoichiometry (XY204)
=(Fe,Mg,Si,Ca,Mn) (Fe,AI)2 04

Recalculation of Fe203 and FeO in SFCA assuming a M25036 structure
Step 1:
Calculate the mole cations from the chemical analyses shown in TABLE A
Step 2:
Recalculate the mole cations to ensure that the sum of the cations equals 25
Step 3:
Determ ine the mole oxygen anions associated with the cations as calculated in step 2
Step 4:
mole Fe3+ cations
Step 5:
%Fe203 (mole Fe3+ cations x total mole cations / 25) x 160 x 0.5
therefore, %Fe203 = 16.06 x 1.39/25 x 160 x 0.5 = 71.43
Step 6:
mole Fe2+ cations
Step 7:
%FeO (mole Fe2+ cations x total mole cations /25) x 72
therefore, %FeO = 0.24 x 1.39/25 x 72 = 0.96
Step 8:
Recalculate to give results in Table B
Step 9:
Accordingly, SFCA Stoichiometry (M25036)
=2 x (36 - total mole oxygen anions) =2 x (36 - 27.97) =16.06
=
=mole Fe2+ cations calculated in step 3 - mole Fe3+ cations =16.30 - 16.06 =0 .24
=
