In this paper,a rough titanium concentrate in Yunnan was taken as the research sample to increase its titanium content and to decrease its content of calcium,magnesium,silicon,aluminum and other impurities.

The trial researches are conducted separately with coarse-grain flotation without grinding and fine-grain flotation after grinding for crude titaniferous concentrate with TiO2 grade of about 33 percent.

The microwave-absorbing characteristics of ilmenite concentrate,coke,oxidized ilmenite concentrate and composite additive were investigated by means of microwave cavity perturbation,and their temperature rise curves were measured.

This paper deals with four methods of using ilmenite concentrate in Chengde:1) The direct use of ilmenite for the feedstock of producing titanium dioxide by sulphate process.

Using the Panzhihua ilmenite concentrate and the analytically pure zinc oxide as raw materials,photocatalytic powders were prepared by solid reaction calcinations process.

Microwave-absorbing characteristics of mixtures about different proportions of carbonaceous reducer and ilmenite in microwave field;

A thermodynamic analysis of the reduction smelting of ilmenite;

ilmenite,titania slag,titanium sponge titanium metal,titanium dioxide is analysed,the technic & economy index and market of titanium production is estimated,capital management,marketing research,strategic league,enterprise culture strategy are put forward.

High iron and low silica sintering techniques of titaniferous iron concentrate;
