he results of laboratory, industrial and calculation researches of physical,

chemical and thermophysical processes at the oxidizing roasting (sintering

and pelletizing) of the titaniferous rawmaterials are considered. The estimation

of influence of metallurgical properties (reducibility, durability, softening and

melting temperatures of roasting ores) on processes heat and mass exchange

at the reduction in the blast furnace (two-dimensional fields of gas and charge

temperatures, degrees of iron reductions, cohesion zone) is executed. Titan-

bearing ores with the various TiO2 content are investigated. Tests of ores are

provided by ores of the current production in theGusevogorsky deposit (average

test), and also ores from separate production of ores - is low titanium and

is high titanium. Ores of the Kuranakhsky deposit, the Tebinbulaksky deposit

(Republic of Uzbekistan) and high titanium ores of the Medvedevsky deposit

and the Yaregsky deposit allowing receiving pigmentary titanium dioxide are

also considered. Processing of the specified ores assumes so-called schemes

«blast furnace - converter» and «metallization - electro melting», including

oxidizing roasting of ore concentrate with receiving agglomerate and pellets.

The micro X-ray diffraction phase analysis and magnetic characteristics of

samples is made. The results of industrial tests on change of metallurgical

properties of agglomerate and its influence on blast furnace indices are given.

Technical and economic indices of blast furnace smelting of agglomerate and

pellets (consumption of coke and productivity, chemical composition of cast

iron and slag), received from a concentrate of the Kachkanarsky deposit, are

calculated. The mathematical model of blast furnace process is considered.

As a whole possibility and reasonability of processing of titaniferous ores with

the different content of titanium dioxide and receiving vanadium containing

cast iron and the slag containing titanium dioxide is shown. Work is executed

with financial support of the State Task of Institute of Metallurgy of the Ural

Branch of the Russian Academy of Sciences, the Project No.0396-2015-0081

and the Russian Foundation for Basic Research, the Project No.16-08-00062
