The experimental conditions for measurement on the content of aluminium, calcium, magnesium, manganese, phosphor, silicon and titanium using ICP-AES method according to GB/T6730.63—2006 have been tested and analyzed. In the experiments the iron ore sample is decomposed and extracted using sodium carbonate/sodium tetraborate with proper acidity as the flux and then a working curve is drawn up using extremely pure ferric oxide (F2O3) as the primitive. And in the end the correlation coefficient r attains to 0.999 and above.
