Flotation and foam separation processes are used in the beneficiation of ores containing layered silicates. The difficulties that arise with such beneficiation can complicate the overall concentration process. It is important that the process of flotation and foam separation occur under conditions of initiated or simultaneously imposed vibration. Such vibration can affect the behavior of the suspension (negatively or positively). Studying the vibration parameters applied to the suspension can help solve technological problems that arise during the concentration of ores containing layered silicates. In the present work, the behavior of a three-phase colloidal system under conditions of oscillation of a vessel with an external vibration exciter is studied.

The largest-scale processes using foams are flotation and foam separation in mineral processing, as well as waste and circulating water conditioning processes in various industries. It is an essential feature of industrial flotation processes that they occur under initiated or incidental superimposed vibration. This paper presents an evaluation of changes in a foam layer for a two-phase system of air and a water solution of a surfactant under oscillations of the vessel with an external vibration exciter.

The relevance of this study is determined by the fact that the Far East, due to restrictions dictated by natural and climatic conditions, remoteness from developed settlement centers, is the most problematic region of the country to ensure food independence. The paper analyzes the development of agriculture in the context of the implemented agrarian policy to ensure food security in the region. The Amur Region, which has the most favorable conditions for the development of agriculture, among the subjects of the Russian Federation included in the Far Eastern Federal District, was chosen as the research site. It is revealed that currently the implemented policy does not ensure the achievement of the goal in terms of food selfsufficiency of the region with the main agricultural products. It is concluded that it is necessary to strengthen measures of state support for the agro-industrial complex of the region
