“…Te proposed methods of rhenium extraction from technogenic industrial products include oxidizing roasting for transferring rhenium into the gas phase in the form of higher oxide Re 2 O 7 or leaching in the presence of oxidizing agents to obtain productive solutions of rhenium. Potassium permanganate, manganese concentrate, calcium and sodium hypochlorite, hydrogen peroxide, and other oxidants are used as oxidants [11][12][13][14].…”

The article presents the results of oxidative leaching of lead sludge from copper production in order to extract rhenium into solution. The optimum regimes for product leaching man-made product in the presence of sodium peroxocarbonate Na2CO3·1.5H2O2 has been established: Experimental work was carried out under the following conditions: oxidant consumption 5% by weight of the raw material, leaching temperature 70°C, duration 30–60 minutes, stirring speed 200 rpm, and the ratio of liquid to solid S : L = 1 : 3. The degree of extraction of rhenium into the solution is 95–97%, and the content reaches 500–520 mg/L Re.
