Abstract The results of investigations into Pb withdrawal with a NaCl solution from the slime of sulfuric-acid production of the Balkhash copper-smelting plant (BCP) to produce a sediment suitable for physical studies of the material composition of Se and other elements contained in the slime that are of interest from the viewpoint of their recovery, in particular, Re, I, and Hg, are presented. Conditions were found that make it possible to obtain a sediment containing, wt %: 40.03 Se, 1.13 Re, 2.86 I, and 4.96 Hg.
