The reduction of titania-ferrous ore (ironsand) containing 57.2 mass% of iron and 7-8 mass% of TiO 2 was investigated in isothermal experiments using H 2 -Ar gas mixtures in a laboratory fixed bed reactor in the temperature range from 973 to 1 373 K. The degree of reduction was measured using an on-line Dew Point sensor and the samples in the course of reduction were characterized using SEM and XRD analyses. The complete reduction of iron oxide in the ore by 25vol%H 2 -Ar was achieved within 60 min at temperature higher than 1 123 K. At 1 173 K, the reduction rate increased with hydrogen content in the reducing gas up to 25vol%H 2 . The composition of samples after 2-h reduction by 25vol%H 2 -Ar depended on the reduction temperature. Below 1 073 K, the final sample contained iron and iron-titanium oxides. At temperatures above 1 173 K, the final sample was composed of iron and titanium oxide. The reduction path at temperatures above 1 173 K is suggested as follows: Fe 3-x Ti x O 4 →'FeO'+Fe 3-x-δ Ti x+δ O 4 →Fe+Fe 3-x-δ Ti x+δ O 4 →Fe+xTiO 2 , (0
