The results of physical, chemical and technological researches are viewed. It is shown that unchanged fine-sized micas do not yield to macro crystalline the same varieties by their complex properties. The micas from old terraces have slight changes in such properties in comparison with new mined and so could be used on equal terms. Main criterions of quality and technoloqical properties were presented. It is offered to define the tenor in layers (ores) using technological ways of concentrating and it gives us the possibility to take it into account not only with sizes of crystals 20+5 mm, but 5+0.0 mm too. It would let us increase the reserves of minerals in range of 4-8 times in case of their overestimation. The elaboration methods of schematic diagram of producing mike concentrates 20+0.0 mm. Work contents, based on technological mineralogy on stages of geological exploration and on geological technological mapping, was recommended. Substantiation of complex use perspective of the main mineral, mica ores and overburden, which widens the assortment of production and increases (about 2 times) economical efficient of using the bowels and their total cost.

The results of physical, chemical and technological studies are discussed. They have shown that unaltered finely crystalline micas are not inferior in complex properties to macrocrystalline micas of the same varieties. Mica from old spoil heaps change their properties slightly in comparison with newly-mined and could thus be equally used. The basic criteria of quality and technological properties are presented. This will enable to estimate the amount of small-sized mica in layers (ores), using technological methods of dressing. This, in turn, will allow us to consider it with crystal sizes of 20+5 mm and 5+0.0 mm. We will be able to increase mineral reserves 4-8 times, if they are overestimated. Methods for development of schematic diagram of dressing to produce 20+0.0 mm mica concentrates are proposed. Types of work, based on technological mineralogy at geological exploration and geological-technological mapping stages, are recommended. Arguments are provided in favour of the multi purpose use of the main commercial mineral, mica ores and overburden, which expands the assortment of products and doubles the economical efficiency of the use of mineral resources and their total cost.

The article presents the methodical scheme of definition of the geological-economic importance of displays of quartz raw material at early stages of geological prospecting. Integrated estimations of development perspective on the basis of correcting parameters to the base cost are developed and recommended for application at calculations of the starting value of licensed search objects.

A complex of low-cost express methods was proposed for the preliminary estimation of the quality of natural quartz during early stages of geological prospecting operations. Combined laboratory investigations provide a means for the comprehensive assessment of the quality of natural raw materials and reject their varieties with poor processing properties.

Structural impurities in quartz are practically unremovable during quartz dressing and are, therefore, responsible for the dressability limit of quartz. The study of structural impurities at the early stages of appraisal of quartz deposits is one of the most essential criteria for assessment of quartz quality. The results of the study of structural impurities in different genetic types of Karelian quartz are presented. It has been found that quartz, metamorphosed at low temperatures to form secondarily recrystallized quartz, contains a minimum amount of structural impurities, whereas granulated quartz is most heavily contaminated with structural impurities.

The dielectrical properties of the cakes of the nonconventional types of quartz-feldspathic rocks were studied to reveal new types of raw materials for electrical porcelain production. It has been found that with an increase in the amount of a potassium oxide-enriched glass phase, which is the case for Yeletozero halleflinta and syenites, dielectrical properties (tg, lg) improve and -indices are close to those of pegmatite. Considering their dielectrical properties ( 6.5;

For quantitative evaluation of thermal stability of a shungite rocks the strategy for determination of a thermal stability index of these rocks was offered. The strategy does not require a complex labware, but the method permits to reliable determine a raw material quality.

Appearance of the automatic image analyzers, autogoniometers, R-microtomographers and neutronograpjic structure spectrometers rapidly increased the interest to the rock stereology as well as to their consideration using modern synergetical ideas combined with mathematical apparatus of the graph and fractal clusters theories.

In the article one can observe the first steps of the revealing and visualization of frustums while macrophisiographical petrographical analysis of several rocks. Frustumation has been firstly revealed in several samples of the Karrara (Toskana, Italy) statuary marble under the influence of short-wave (254 nm) ultra-violet emanation of mercury-quartz high-pressure lamp SVD- as a source of luminescence stimulation, and then in numerous samples of several rocks of different genesis. Characteristic dimensions and outlines of the frustums within the rocks investigated are discussed. The smallest frustums by the amount of mineral grains they contained have been observed in monomineral rocks: datolitic scarn, silicate quartz pegmatite nucleus, galite and statuary marble (about 125-300 grains in volume). The greatest frustums have been observed in polymineral rocks: medium grained amazonite-albitic and pegmatoid rare-metal granites (more than 5000-6000 grains in volume). As it is shown, the later subsequent processes (amazonitization, albitization, and quartzitization in granites as well as ore mineralization development in alkaline granite) inherited the frusums boundaries as weakened zones within these rocks and to some extent underlined it by their more abundant occurrence.

The effect of the typomorphic characteristics of major rock-forming minerals on the physico-mechanical properties of the rocks used as facing stone is discussed. Karelian granite deposits are used as examples.

The chemical composition, mineralogical-petrographic and physico-mechanical characteristics of various types of facing granites were studied and the results obtained are presented. Changes in physico-mechanical parameters are shown to be caused chiefly by the composition, typomorphism and percentage of feldspar and the presence of dark-coloured minerals in granites.

The authors show that the diagrams developed can be used to assess the homogeneity and quality of raw material for basaltic technologies at the early stages of geological prospecting and to calculate the additives required to make the compositions of raw material optimum for the manufacturing of various products.
