Purpose. The development of cheap and simple method of the low dispersed titan powders production Design/methodology/approach. The titanium production in the Ukraine and basic difficulties of the low dispersed powders making was brief reviewed. The production processes of low dispersed titanium oxides powders preparation from the titanium sponge and titanium industry waste were worked out, using methods of the bacterial leaching and mechanical powdering with the dispersive liquid. The elemental and phase composition and also the grain-size properties of the obtained samples were researched. Findings/resume. As a result of researches we offer the method of the low dispersed powders of titan production from the titanium sponge and titanium industry waste, using methods of the bacterial leaching and mechanical powdering with the dispersive liquid. The basic advantages of bacterial leaching method with the use of the revolving disintegrator are simplicity of instrument design, rapid bacteria reproduction ability, solution regeneration, the bacterial leaching speed increase as compared with the chemical leaching, reagents cheapness.

Keywords: titanium, nanopowder, bacterial leaching, dispersive liquid.
