Production of Iron, Titanium Dioxide Modofocations and Titanium

Conditions for the reduction of titanium-magnetite concentrates (main components are Fe 52–54 % and TiO2 5–7 %) by natural gas for obtaining iron powder and titanium fraction were studied. Based on the theory of granulation in the drum apparatus, granules with 25 % of soda fluxing additive with optimum diameter, humidity, strength and porosity were obtained. It was found that the reduction reactions in the temperature range of 1143–1198 K are carried out if a mixture of hydrogen and carbon monoxide is added to the natural gas in amount of 15 vol %.

Peculiarities of Producing an Electrolytic Iron Powder from Rolling Manufacture Waste

The electrolytic iron powder with controlled shape and size of particles and required structural, physical and functional properties was synthesized. The electrolytic precipitation of dispersed iron was carried out using a steel soluble anode and a titanium cathode. Sulfate electrolyte was used; the shape of the cathode was a plate; the electrolysis time was 1 h. Experimental studies were carried out using correlation-regression analysis. The average particle size and morphology were determined using optical microscopy.
