Amount of chromium atom: 52 iron atomic weight: 56

u Cr2O3 : M %

u Fe2O3 : N %

u Cr ×2 / Cr× 2 + O ×3 =0.6842 u Fe ×2 / Fe× 2 + O× 3 =0.7

Cr / Fe = M × 0.6842 / N × 0.7

example:

Set a batch of ore containing 50% Cr2O3 , Containing 15% Fe2O3 , calculating ferrochrome ratio

M = 50% N = 15 %

Cr / Fe = M × 0.6842 / N × 0.7 = 50% × 0.6842 / 15% × 0.7 = 0.342 / 0.105 = 3.25
