Abstract
This article analyzes methods for extracting rhenium from solutions, including the processes of precipitation of potassium perrhenate and ammonium perrhenate, precipitation in sulfide, and selective dissolution in water. Technological schemes for the extraction of rhenium, chemical mechanisms of the dissolution process, and optimal conditions are presented. The precipitation processes of potassium and ammonium perrenates, ion exchange methods, and the effectiveness of water leaching were studied in a comparative aspect. In the process of rhenium extraction, the influence of temperature, reagent concentration, and other important parameters is studied. The research results are of great importance for the rhenium mining and processing industry.
