This is one of the largest industrial enterprises of the region known for its production experience, highly qualified team, and the developed infrastructure. The Zhezkazgan copper smelting plant consists of the following main shops: Since the first electrolytic copper was produced at the Zhezkazgan copper smelting plant in February 1971, a lot has changed at the enterprise, in particular, the process equipment has been modernized, but one thing remains unchanged – labor enthusiasm, professionalism, and a close-knit team. In 2015, the plant began pilot testing of an innovative technology for the processing of concentrates from low-grade poor copper-sulphide ores. The introduction of hydrometallurgy allowed to mine ores with low copper content, as well as to replenish the raw material base and extend the production activity of the Zhezkazgan site by more than 50 years. This year it is planned to start construction of a pilot plant for hydrometallurgical processing of copper concentrates. 31,67 mln dollars will be spent for the introduction of hydrometallurgy. The term oа the implementation of this project – from February 2014 to March 2017.
