Abstract:Three methods for determination total iron in iron ore were described and compared in this paper. The tita-
nium trichloride, potassium dichromate and neutral red were selected as indicator. At the same time, the temperature,
solution acid, medium acid, the selection for indictor and elimination of coexisting were all studied in this experiment,
while the hazards posed by mercury was also avoid. At last, the results for analysis standard samples were very satis-
