East Kazakhstan is loed in the region called Rudny Altai, which means "Ore Altai". Modern UstKamenogorsk is the center of the metallurgy of nonferrous metals of Kazakhstan. [11] The main building was designed by Anatoly Konstantinovich Sidorov. Construction of the building was completed in 1965.
Polymetallic ores in Russia are also found in the Far East. Currently, work is underway to extract such minerals in three fields: Nikolayevsk, Verkhny, and Partizansky. Mineral raw materials from deposits of the Far Eastern Region of the Russian Federation are distinguished by a high content of lead, zinc, gold, silver, tungsten and tin.
