In the face of global depletion natural resources and increasing demand for sustainable development, processing industrial waste, such as tailings from plants, is becoming essential. This study focuses on combined technologies, including flotation concentration concentrate processing, allowing efficient recovery valuable components. aims to investigate possibility thermochemical enrichment opening low-grade copper plants with transfer silicon rhenium in form silicate-ions perrhenate-ions into a solution output multifactor multiplicative model obtaining tabular nomograms. Multifactor experiments rough concentrates made it possible construct partial dependences extraction obtain Protodyakonov–Malyshev models these processes nomograms over wide range temperatures, durations, alkali-to-concentrate ratios determine maximum rates. The developed establish optimal intervals changes sintering parameters, providing high rates (over 85% 98% rhenium) during subsequent water leaching. Optimal conditions (temperature 350 °C, duration 90 min, ratio NaOH = 1:2) ensured up solution. rate reduces need primary raw materials positively affects production’s environmental performance because minimizes amount waste disposal.
