Ural State Mining University is situated in Yekaterinburg, Russian Federation. It was founded in 1914. In 1917 Nicholas II signed an order titled "On keeping of the Yekaterinburg Institute of Mines under the patronage of His Majesty the Emperor and on giving to this educational establishment the title of The Emperor Nicholas II Ural Institute of Mines".It is the oldest establishment of higher education in the Middle Urals. It offers education in geology, geophysics, engineering and management of mining, geological prospecting. The university offers dozens of graduate and postgraduate programmes. The geologists of the university have discovered hundreds of deposits in Urals and Siberia. Wikipedia.

The issues of metal product balance calculation at concentrating plants are considered. The following recommendations are developed. Product recovery may be calculated by two methods: through using component mass in concentrate and feed ore for calculations and through using component mass in concentrate and tailings for calculations. The main problem consists in coordination of indicators used in calculation, taking into account product accumulation in tanks and bins. If head sampling is unavailable, product recovery may be calculated on the basis of produced and accumulated masses of concentrates and tailings. Tailings in this case should include all products that are not related to con- centrate under consideration. Product recovery is equal to sum of process recovery and relative imbalance. Product imbalance may be expedi- ently divided into two parts: occasional and non-occasional. Since valuable component mass in concentrates is also determined with errors, for correction it is expedient to distribute occasional part of imbalance proportionately with each product contribution to component mass in product balance and relative errors in their mass fraction sampling. It is expedient to distribute non-occasional part of imbalance in accordance with positive and negative constituents of sampling imbalance errors with respect to ore and tailings, and also concentrate. It is not necessary to include products in circuit into imbalance distribution.

The effect of thermal destruction of coal on the parameters of reduction of iron oxides from concentrates has been experimentally studied with an STA 449C Jupiter differential scanning calorimeter equipped with a QMC 230 mass spectrometer. It has been found that thermal destruction increases the reduction rate and decreases the temperature of the beginning of the process because of an increase in the reduction potential of the gas phase and in the specific surface area of coal. The products of thermal destruction of coal hardly participate in the carburization of the reduction product. © 2015 Pleiades Publishing, Ltd.

The electronic structure of carbon shells of carbon encapsulated iron nanoparticles carbon encapsulated Fe@C has been studied by X-ray resonant emission and X-ray absorption spectroscopy. The recorded spectra have been compared to the density functional calculations of the electronic structure of graphene. It has been shown that an Fe@C carbon shell can be represented in the form of several graphene layers with Stone-Wales defects. The dispersion of energy bands of Fe@C has been examined using the measured C Kα resonant X-ray emission spectra. © 2012 Pleiades Publishing, Ltd.

We discuss possibility for observation and identification of weakly non-Newtonian rheological behaviour at small shear rates. Some mathematical models of experiment and data processing are given. As an example, we analyze capillary, inertial and oscillating-cup viscometers suitable to study high-temperature melts. © 2013 AIP Publishing LLC.

In this paper we describe the technique of localization of weakened zones in the geological environment. New interference method based on the transfer traces of common offset gather sections on the various points of profile and summing of this calculated traces on each point. Operator of seismic trace transformation based on inversion of the double square root equation. In common case this algorithm is analog of pre-stack migration procedure but also this procedure can be apply for selection of scattered components of the seismic wave field.
