| Abstract: | By using sodium peroxide as flux,melting sample in a ferric crucible quickly,and dissolving with nitric acid, SiO_2,CaO,MgO,Al_2O_3 in iron ore can be analyzed systematically.Compared with the national standard method,the proposed method has more advantages such as operating easily,good accuracy,rapid procedure,low cost,wide range of determination and so on.It has been applied to the systematic analysis in iron ores with satisfactory results. |
