The goal of the research is an attempt of optimization of the hydrometallurgy-based zinc production line, consisting of three stages: mixing of raw materials, oxidative roasting and leaching. The output product of one stage is an input to the next stage. Goal of mixing is preparation of zinc concentrates mix on the basis of zinc concentrates originated from different mines. The output semi-product of the next stage, the oxidative roasting process, is calcine, which is the input of the leaching. The result of the leaching is zinc sulfate solution and the goal of leaching is to carry out the maximum amount of zinc to solution. The preliminary step of any optimization is modeling of the analyzed processes. Modeling of considered three stages of zinc production line, based on the real industrial data of one of zinc production plants, was performed using different techniques. The elaborated models were the basis of the optimization for given objective functions of each of the production stages. The optimization methodology of multi-stage processes developed by the authors was applied. Obtained results of modeling and optimization are presented.

Informacje na temat otrzymywania cynku przedstawiono w starożytności (Europa, Chiny, Indie). Scharakteryzowano najważniejsze metody produkcji cynku: hutniczą (ISP - Imperial Smelting Processes) i hydrometalurgiczno-elektrolityczną. Omówiono pierwotne i wtórne źródła cynku oraz produkcję tego metalu w głównych ośrodkach wydobycia rud Zn-Pb w XIX i na początku XX wieku. Zwrócono uwagę na rolę złóż śląsko-krakowskich w bilansie globalnej produkcji cynku, na przestrzeni ostatnich wieków. Przedstawiono zmiany wielkości produkcji cynku w XX wieku oraz zmiany cen tego metalu na Londyńskiej Giełdzie Metali (LME). Wskazano, w jakich dziedzinach gospodarki stosowany jest cynk oraz jakiego rodzaju odpady zawierają znaczące ilości tego metalu.

The paper presents the information on the zinc production in antiąuity (Europe, China, India). The most important methods of zinc production: metallurgical (ISP -Imperial Smelting Processes), hydrometallurgical and electrolytic technologies were described. The primary and secondary sources of zinc and production of this metal in main centres of mining operation in XIX and in the beginning of XX century were discussed. It was considered the importance of Silesian-Cracovian deposits in global balance of zinc production over last ages. The changes of zinc production volume in XX century and price changes of this metal in the London Metal Exchange (LME) were presented. There were showed the industrial sectors in which zinc is applied and the types of waste containing significant metal quantity.
