Research and determination of parameters for extracting valuable components from technological waste

Abstract

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.
