This research paper addresses the increasing demand for ammonium perrhenate and pure metallic rhenium, emphasizing the importance of developing effective methods for extracting these valuable components from technological waste. The authors detail the processes involved in sorption and leaching of rhenium from molybdenum production waste using various sorbents under static and dynamic conditions. Experiments reveal that new granulated sorbents, particularly P-MDA-6, exhibit superior extraction capabilities compared to traditional methods. The paper also discusses the chemical mechanisms behind rhenium and molybdenum leaching and highlights the role of environmental considerations in developing sustainable extraction technologies. The findings contribute to advancements in metallurgical processes and waste management strategies in Uzbekistan’s industry. In global practice, the demand for ammonium perrhenate and chemically pure metallic rhenium is increasing every day. In this regard, the development of new methods for obtaining metallic rhenium and its chemically pure compounds by processing technogenic waste, improving existing technological processes, obtaining high-quality products from mineral raw materials, as well as comprehensively studying their physicochemical and technological properties and developing an environmentally friendly technology for extracting rare metals, is of great importance.

The article presents the experiments of scientific study of the temperature changes of the pond layers at the given solar radiation values inside the solar pond device modeled using Comsol Multiphysics. The developed model of the solar pond with simplified geometry dimensions changes the sign of the experimental calculation in a positive direction, which helps to study and optimize the energy accumulation process. This research shows that computer modeling can be used to study and optimize the solar pond energy storage process. In addition, the results of this modeling can be used to improve the solar pond device and develop its new technologies. The models obtained from the 3D study of the process using the Comsol multiphysics program are analogs of the three-dimensional cross section in the vertical part of the solar pool. It has been shown that the bottom energy storage layer of the solar pool rises up to 60 ℃ when the concentration of the salt water mixture in the solar pool device varies around 25-30% and the energy storage reaches its maximum value when the solar radiation reaches its maximum value.
