History of Krastsvetmet Research and Development
Early research and development at the plant coincided with the stage of the plant’s establishment, when production technology and product analysis methods were developed in liaison with the scientists of the Institute of General Inorganic Chemistry (IGIC) of the Academy of Sciences of the USSR and a group of scientists and engineers — prisoners of the Gulag, who were repressed by the Stalinist system and worked at the plant.
Major achievements during the establishment period of production are associated with the names of:
- I.Y. Bashilov, a professor and scholar in the field of chemistry, rare elements and precious metal technology;
- R.Y. Muller, a professor, who developed the reduction technology for gold production;
- V.V. Nadler, a theorist and practitioner in the field of spectral analysis;
- V.K. Kostrykin, the developer of the chlorination process for platinum containing materials;
- S.M. Anisimov, a professor, a scientist in the field of non-ferrous metals.
The contribution of these scientists formed the scientific and technical potential, which became the basis for the plant’s research and development establishment. In 1944–1945 a research department was formed as a part of the Central Plant Laboratory. In 1965, based on the department, a development and production facility was established, with the main task of improving production technology. Scientists of this workshop, together with operating engineers, implemented the fundamental processes of refining such as:
1969 – extraction technology for the separation and refining of accompanying metals;
1970–1974 – perchloric technology for the dissolution of raw materials and industrial products;
1985 – technology to polish rhodium using the chloro-thermal method;
1989 – Iridium refining technology;
1996 – new, effective gold and silver refining chemical technology.
