Since the mineral resources are close to exhaustion, refractory ores are now involved in processing. Their main features are low content of useful components, complex structure, unstable mineral composition, lack of contrast processing properties. A complex of physical methods was implemented for the ore quality assessment, namely optical and electron microscopy, electron microprobe analyses, X-ray powder diffraction and X-ray CT. The results obtained offered the complete and accurate information about composition and structure of minerals. We point the priority approaches to studying such ore are methods of quantitative mineralogical analysis. The refractory titanium-containing iron ores and current pyrite tailings present a bright example of the technological mineralogy potential. The results of mineralogical and technological evaluation of natural ore natural and mining waste are given. The influence of the morphological characteristics and heterogeneity of the titanomagnetite composition on the ore processing properties was determined. The classification for anisotropy of titanomagnetites by titanium content as a result of the crystallization conditions and evolution of the mineral was developed. Analysis of titanomagnetite heterogeneity allows predicting grains disclosure effectiveness and permits to trace the mineral composition variability of different grain size material. The composition study of current tailings from the Southern Urals sulfide ore deposits makes it possible to trace the evolution of their technological properties ontogenesis. The granular composition of clastic material, morphological characteristics and chemical composition of minerals and the size distribution of useful components govern the choice of the method for ore dressing and the technology of tailings processing. A profound study of the mineralogical features of deposits by a complex of modern methods of mineralogical analysis facilitates the identification of process properties of natural minerals and mining waste.
