The history of Novotroitsk goes back to the beginning of the 20th century. Several families of peasants/immigrants from Ukraine settled near Silnov
khutor and named their settlement Novotroitsk. Two more khutors Akkermanovsky and Beloshapochny as well as Khabarnoye
stanitsa located nearby. The 1930s were the time of rapid
industrialization in the Soviet Union.
Alexander Fersman, a well-known academician and geologist, in his treatises described the abundance of mineral deposits near Orsk neighbourhoods and called Orsk-Khalilovo area the "true gem of the Urals." In the fall of 1929 geologist Joseph Rudnitsky discovered the Khalilovskoye
hematite field. Khalilovskoye ores contained
chromium,
nickel,
titanium and
manganese. Industrial tests confirmed its quality. In June 1931, the Government adopted a decision to start the construction of metallurgic plant based on resources from Khalilovskoye ores and
Karaganda coal basin. The end of construction was scheduled for 1936. During this period the first builders arrived to Novotroitsk village. In 1935 the construction was suspended and only in the spring of 1939 after the
18th Congress of the All-Union Communist Party the resolution was adopted "... to begin the construction of new metallurgical plants (at Khalilovskoye and
Bakalskoye ores)". In the summer of 1939 the board of the
People's Commissariat of Ferrous Metallurgy adopted a resolution, which says: "... to select the Novotroitsk area as a place for Khalilovo metallurgic plant construction...". In 1941 Novotroitsk was granted the status of
urban-type settlement. During the next three years the first school and hospital were built. Novotroitsky District, comprising Novotroitsk and Akkermanovka villages, was created in 1944. On April 13, 1945, Novotroitsk was granted the status of town. On March 5, 1955, the first
cast iron was produced at the metallurgic plant. The cement factory was launched in the same year. In 1982 the population of Novotroitsk climbed over 100,000. During the Soviet period a lot of cultural, sports and recreational institutions were founded including two
palaces of culture, several cinemas, schools, colleges, hospitals, public park, two stadiums, swimming pool, consumer service center. In 1992 formerly state-owned metallurgic plant was converted into joint-stock company. In 2002 the South Ural mining and processing company was founded. Eight years later the company launched a new cement plant within a few kilometers from Novotroitsk near Akkermanovka village. According to the Russian Government order, in 2014 Novotroitsk was included into the list of
monotowns with the most complex social-economic situation. By the Russian Government decree, in 2017 the new priority development area was created in the town. As at August 2021 ten companies has become the residents of the priority development area. ==Administrative and municipal status==
