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.
