ABSTRACT
In job the results of study of material structure tests of titan-magnetite iron ore of a deposit Tebinbulak are given. Industrial - valuable component is iron. On the basis of study of material structure for processing ore it is possible to recommend gravitation and magnetic separation.
Keywords: titanium-magnetic, tebinbulak deposit, temirkan, vanadium, material.
In the Republic of Uzbekistan there are iron-containing deposits Temirkan in the Jizzakh region, Surenata in the Tashkent region, Tebinbulak in the Republic of Karakalpakstan, etc.
Uzbekistan has significant reserves of titanium-magnetite ores at the Tebinbulak deposit in Karakalpakstan. The preliminary estimated reserves of the deposit are 452.3 million tons with the following chemical composition: iron-15-16%, titanium-2-3%, vanadium-0.15%. The reserves are estimated at 3.5 billion tons [1-8].
Titanomagnetite is a type of ore raw material with a complex composition, which contains iron oxides, titanium dioxide and vanadium pentoxide.
The technology for processing titanomagnetite ores differs from the technology for beneficiation of iron ores in that during the processing it is necessary to separate vanadium and titanium oxides from iron oxides [9-16].
Until now, iron ores have not been processed in the republic. In the coming years, it is planned to build an enrichment plant at the Tebinbulak deposit with subsequent processing of the concentrate at a metallurgical plant in the city of Bekabad.
We have studied the material composition of a titanomagnetite ore sample taken at the Tebinbulak deposit.
The ore sample was prepared for research according to the standard method (Fig. 1). In the process of preparing a sample, an average sample was taken from it for spectral and chemical analyzes [17-23].
The results of the semi-quantitative spectral analysis of the average ore sample are shown in Table 1.

To clarify the distribution of iron by size classes, the average sample with a particle size of -3 + 0 mm was subjected to sieve analysis, the results of which are shown in Table 3.

Based on the results of sieve analysis, it can be concluded that iron is unevenly distributed throughout the sample.
As a result of studying the material composition of a sample of titanomagnetite ore from the Tebinbulak deposit:
Iron is a valuable component of the ore, titanium and vanadium are associated. The ore characterizes the titanomagnetite type [24-27].
The iron content in the sample is 13.5%. Associated useful components - titanium dioxide-1.74% and vanadium pentoxide-0.06%.
Sulfur and phosphorus in the sample are insignificant.
The main ore minerals of the sample are titanomagnetite, ilmenite, hematite and titanite [28-30].
Based on the study of the material composition for ore processing, it is possible to recommend the methods of gravity and magnetic separation.
