In March 1938, testing of the equipment of the concentrating factory began, and it produced the first concentrate. In July, the first reverberatory furnace went into service — the foundation of metallurgical manufacturing. On 24 November 1938, Balkhash's first copper was shipped out. A plaque was placed at an entrance of the smelting plant commemorating this event, and 24 November is considered the birthday of the smelting plant. The ingot of Balkhash's first copper is kept in the Museum of the Revolution in Moscow.
