In this paper, an innovative process for the extraction of selenium from substandard selenium-containing raw materials obtained at copper smelters is proposed. The process has been tested on an enlarged scale under the developer's conditions and implemented on an industrial scale for the first time in the Republic of Kazakhstan. The implementation of this development has enabled the Republic of Kazakhstan to transition from a country reliant on raw materials to a new level: a country producing high-tech products in demand on all global metal markets. This work was awarded a high Government award in 2025 – the Al-Farabi Prize in Science and Technology.
