Classification of methods of reproduction of mineral raw material is given, the basic problems and prospects in working off technogenic and non-commercial mineral raw material and an opportunity on this basis of completion of a mineral resources base are shown.

Physical and chemical ways of decreasing a geoecological load of technogenic deposits have been scientifically proved. The grouping of the processes providing nature protective formation of technogenic deposits has also been offered.

The necessity of technological properties exploration for complete utilization of mineral reserves from natural and technogenic deposits is emphasized. Applied micro and nanostructural investigations of rocks on the base of mineral liberation prediction improve control of mining and mineral processing of ores with complex structures and composition. Results could be used in GIS with geotechnical and geometallurgical mapping to accomplish mining optimization of complex mineral resources with minimisation of environmental consequences.

In the article there are presented the results of studying the establishing of the energy block structural parameters affect on hydraulic hand breaker IG-4601 duty characteristics. There are determined the rational values of structural parameters

There is a basic opportunity of use of cyanide containing reagent, received from wastes of phosphoric industry, for gold leaching of oxidated gold containing ores.

Исследована термодинамика и кинетика взаимодействия фенакита с серной кислотой и созданы предпосылки для разработки промышленных методов непосредственного сернокислотного вскрытия данного минерала.

The technology of the preparation of hardening mixes with complex preparation low-level components on shaker, in disintegrator and the vibromill is described, and also the electrochemical processing, allowing essentially to increase durability of a mix.

In present period technogenic environmental contamination by waste of the mining industry became one of sharp actual problems of ecological safety of many countries. In this respect ecologically especially areas of mountain territories where in significant volumes on different deposits extraction and processing of uranium ores was carried out or conducted are vulnerable.

In this article we are observe dynamic modeling system as base of technology processing construction. Have description of manning managements' targets in case of using these dynamic modeling systems. For example, explained the system of strategically planning for pumping oil. Have interface for connection and integration with externally software and scientific library.

Сlassification of factors of development of the state or municipal university is given. The analysis of problems in educational process, scientific activity, marketing, the finance, human resources, culture and image of university is resulted.
