abstract = "The jarosite type of sediment that occurs in the hydrometallurgical production of zinc represents an attractive research area for the valorization of lead. Intermediate products of zinc metallurgy were used for testing: untreated, roasted and water-washed roasted PbAg precipitate. After a detailed insight into the possibility of processing this type of sediment using the hydrometallurgical process, the choice of means for leaching the samples was made, and in the experimental research a solution of magnesium chloride hexahydrate (MgCl2 × 6H2O) was used. The thermodynamic analysis included the calculation of the standard Gibbs energy of chemical leaching reactions and the construction of the Eh/pH diagram of the stability of lead and accompanying metals in the investigated systems. By examining the influence, ratio of sample mass and volume of leaching agent, as well as leaching time, conclusions were reached about the possibilities of leaching Pb from intermediate products of zinc metallurgy. The optimal parameters of the leaching process in the tested systems were determined, i. e. it was shown that in all three tested samples the maximum leaching of lead is achieved at a concentration of MgCl2 × 6H2O of 4 mol/dm3, for a duration of 60 minutes, at a temperature of 80 oC and a solid:liquid ratio of 1:20.",
