GEOLOGICAL STRUCTURE AND PETROGRAPHY OF KIMBERLITE PIPES
Carried out investigations of geological structure and material composition of the Siberian platform kimberlites indicated complexity and diversity of geologic-tectonic and paleogeographical situations, which should be considered when performing forecast-prospecting works on diamonds in each specific region. Depending on geologic-geophysical and geomorphological situation of kimberlite diatremes’ occurrence specific features of their forecasting and prospecting are determined. Knowledge of material composition of both sought-for diatremes and hosting and overlapping them sedimentary and magmatic formations is an important criterion for prospecting of kimberlite bodies in various geologic-tectonic conditions. Special attention should be paid to typomorphic specific features of both initial and newly formed minerals in diatremes.
Keywords: geology, kimberlites, pipes, Siberian platform, diamondiferous region, typomorphism of minerals.

MINERALOGICAL AND TECHNOLOGICAL ESTIMATION OF ORE FROM THE ANOMALOUS ZONE KOVDOR DEPOSIT
The paper presents the results of mineralogical and metallurgical studies of ore from the Anomalous Zone of the Kovdor baddeleyite-apatite-magnetite deposit. As demonstrated, the ore has a complex geological structure, and contains, along with the major minerals (magnetite, apatite, and baddeleyite) the accessory minerals of the pyrochlore group, hatchettolite and zirkelite. Studies of the mineral and chemical composition of the ore, as well as the metallurgical properties of the ore minerals demonstrated that zirkelite and hatchettolite occur as super-fine intergrowings and are best liberated into the 10-30 µm grain size fraction, so these minerals very easily join the slimes. Thus, due to the natural properties of the host Ta and Nb minerals and metallurgical features of the ore, the development of the extraction techniques for these metals (Ta and Nb) is problematic.
Keywords: Kovdor deposit, Anomalous Zone, apatite, baddeleyite, accessory minerals, gatchettolite, zirkelite.

ABOUT PERSPECTIVES OF STUDYING KIMBERLITE INDICATOR MINERALS
Analysis of the results of carried out investigations of mantle modules in kimberlite diatremes of main diamondiferous regions of the Siberian platform was made. Detailed complex investigations of diamond and its paragenetic accessory minerals allow establishing material-indicative parameters of kimberlite magmatism of various productivity and geologic-structural position of kimberlite bodies, and address issues about primary sources of placer diamonds, as well. The presence in kimberlites of definite groups of depth xenoliths and xeno-grains of their minerals, chemical and geochemical composition of kimberlites allowed formulating a concept about properties of upper mantle formations, being the source of magma for each of distinguished type of kimberlites. Upgrading the line of research on creation of more efficient ore processing flowsheets and providing crystal-integrity technologies, expansion of diamond application areas with consideration of their real structure and physical features, as well as revelation of natural targets with increased quality of diamond raw material, are all related with investigation of primary indicator minerals of kimberlites.
Keywords: diamond and its paragenetic accessory minerals, diamondiferous fields, Siberian platform.

PROBLEMS OF BOXITE PROCESSING AND ENRICHMENT, WASTE MANAGEMENT
The problem of enrichment of aluminum ores is due to the fact that bauxite-forming minerals have similar density, dispersed character and subtle intergrowth. Therefore, the development and improvement of methods for the enrichment and processing of bauxite continue. The work shows the effect of physical and chemical factors on iron minerals with the goal of transforming them into magnetite, to increase the magnetic phase. Influence of various kinds of energetic influences on bauxite raw materials and red mud is established, under which the magnetic properties and phase composition change, the concentrations of certain minerals change.
Keywords: bauxite, red mud, treatment and enrichment of bauxite, utilization of red mud.
