Annotation As you know, one of the significant environmental problems accompanying industrial gold mining is dumps made of associated rocks of gold-bearing ores, in particular, pyrite FeS2. FeS2 is used in small quantities to make sulfuric acid, which in turn is used in the chemical industry. This process is also accompanied by the appearance of unclaimed residual rock ‒ pyrite cinder. All of this has an adverse impact on the environment. One of the ways to solve this problem may be the use of pyrite and pyrite cinder in thermoelectric materials science. In connection with the need to search for new materials for the needs of thermoelectricity, the attention of research ers working in this field has recently been attracted by sulfide minerals and structures based on them. They are widely distributed in nature and, in particular, in the fields of the Transbaikal Territory; are the object of industrial mining; As a result, they are quite cheap. The object of the research is one of the most common representatives of this class of substances – natural pyrite. The subject of the research is the depolarization and relaxation properties of pyrite. The aim of the study is to analyze the features of the change in the resistivity of FeS2 minerals after the end of exposure to single pulses. To achieve this goal, it is necessary to solve the following tasks: to assemble a device for removing the temporal dependencies of resistivity and specific conductivity of composite structures based on natural pyrite; to determine the time dependencies of resistivity and conductivity of the studied compositions; to analyze the results obtained from the point of view of theoretical ideas about relaxation processes under the influence of external factors of influence; cyclic electrical impulses; to assess the practical significance of the observed effects and their applicability in the field of creating generators that convert thermal energy into electrical energy.
Key words Natural pyrite, pulse, electric field, Pulse Polarity, time dependencies, resistivity, conductivity, thermo generator, physical properties of pyrite, thermoelectric efficiency
