APPLICATION OF GAUSS-LAPLASSE AND B(BETA) DISTRIBUTIONS IN A MINERAL GRINDING MODELING ALGORITHM

(STEF92 Technology, 2021-12-20, Sergei Lukichev, R. M. Nikitin, Valerii Birukov, A. Oleinik)

Show more

In this study, the authors have continued investigating the tasks of the joint application of the Gauss-Laplasse and B (beta) distributions to describe the disintegration of minerals of poly-mineral ores, which is associated with the mineral grains liberation, i.e., the release of mono-mineral particles from the aggregates with other minerals. The article presents an approach for a simulation modeling algorithm for disintegration operations of mineral particles in technological flowsheets of mineral processing. Us...

ENSURING THE THERMAL REGIME OF THE ROCK MASS DURING CONSTRUCTION OF UNDERGROUND MINE EXCAVATIONS IN THE ARCTIC CONDITIONS

(STEF92 Technology, 2021-12-20, Viktor V. Nikolaev, Valerii Birukov, Aleksandr Orlov, Yurii Smirnov)

Show more

The work is aimed at creating methodological provisions to substantiate the safe parameters of the thermal regime in permafrost rocks when constructing underground mine excavations in the Arctic region. An idea is to control the thermal regime by creating mathematical models, taking into account the main technological operations during excavations driving. The paper presents the results of experimental studies and evaluates the thermal impact of various technological processes during the construction of mine excav...

KINETICS OF FINE FERROMAGNETIC PARTICLES AGGREGATION

(STEF92 Technology, 2021-12-20, Valerii Birukov, А. С. Опалев, R. M. Nikitin)

Show more

The most important result of the effect of interparticle interactions of ferromagnetic particles in suspensions is the formation of aggregates and modification of their physical properties, which allows changing the kinetics of separation processes. The interest of the authors to this problem is dictated by both its theoretical content and purely applied aspects within mineral processing. Based on the block-structural approach to technological equipment modeling within the framework of the ideal mixing model, a ma...

MATHEMATICAL MODELING OF FERROMAGNETIC PARTICLE AGGREGATION IN IRON ORE PROCESSING TECHNOLOGIES

(STEF92 Technology, 2020-09-20, Valerii Birukov, А. С. Опалев, R. M. Nikitin)

Show more

The paper considers the formation and development of modern ideas in the field of mathematical modeling of the interaction of ferromagnetic particles and external magnetic fields in mineral processing. The implementation of such studies is dictated by the need to identify methods for the analytical representation of the physical laws of the aggregation of ferromagnetic particles, which are a basis for the various technological equipment used in the iron ores processing. The identification is aimed at the use of in...

SIMULATION MODELING CONCEPT OF DISINTEGRATION OF MINERALS BASED ON GAUSS - LAPLACE AND B (BETA) DISTRIBUTIONS

(STEF92 Technology, 2020-09-20, R. M. Nikitin, Sergey Lukichev, Valerii Birukov, Andrey Oleinik)

Show more

This work studied the problem of the joint use of Gauss - Laplace and B (beta) distributions to describe the disintegration of minerals of polymineral ores, which is associated with the liberation of mineral grains - the release of monomineral particles from intergrowths with other minerals. The basic position of the work is the dependence of the result of reducing the size of mineral particles on the energy expended on this process, postulated in the mineral processing theory. This dependence was taken into accou...
