From January 5, 1925 to May 1926, the Georg von Giesches Erben company built a new mine on the German side in the Neue Fortuna A field (using the existing network of previous workings and shafts). The newly established plant was one of the largest and most modern mines of this type in the world at that time. The buildings for the plant were designed by Emil and Georg Zillmann. The cost of building the mine, which was to provide employment for about 3,000 people, was estimated at 7 million German marks. A new mechanical processing plant was also built at the mine, completed in 1928, including a reflow furnace, as well as a flotation department. The new mine was incorporated into the subsidiary Giesche SA. Mining began in 1926 (according to another source, in 1928). The main mining shaft was named Georg von Giesche (see Georg von Giesche; renamed Chrobry after 1945), the other shafts were Förster[30] (later the Postęp shaft at Brzezińska Street), Immergrün, Grenz and Wolfgang. The workings went down to a depth of about 90 and 100 meters. The workings on the border were barred and sealed until 1929, which was later replaced with 15 brick dams. Until 1932, the workings connecting the mine with the neighboring Szarlej Biały plant were controlled by border guards. Despite the fencing of the workings, they were used for smuggling, which was difficult to combat. The extracted ore was sent around 1934 to the zinc smelter in Magdeburg (the smelter started operating in 1934, it was built at the initiative of Georg von Giesches Erben, the city of Magdeburg and the Reich government), where metallic zinc was obtained by the electrolytic method. Since World War II Edit During World War II and the years preceding it, the best ore deposits were selected[4]. In April 1945, the Soviets handed over the inactive mine to the Polish authorities[38]; the partially destroyed mine, together with the enrichment plant, was reopened thanks to the efforts of the Zinc Industry Association in 1946. The crew meetings were held in the Chrobry shaft, while the ore was extracted around 1946 in the Krakus shaft, which belonged to the neighboring Orzeł Biały mine in Brzeziny Śląskie. On October 1, 1950 (according to another source, in 1954), the Nowy Orzeł Biały Mining Plant was renamed the Julian Marchlewski Mining Plant. Since 1947, the deposit in the area of ​​the Bytom protective pillar was mined with dry backfill; the use of backfill was initiated by the Germans. Over time, concrete backfilling of the excavations was used. Since 1953 (or 1954), the only crystalline xanthate plant in Poland operated in the plant, which was used as collecting reagents in the flotation process. It was also used as a catalyst in the production of synthetic rubber. Lead ore after the flotation process (probably using xanthates of its own production) and zinc ore were transported in the 1950s to the merged Szopienice Zinc Plants (lead ore to the former Walther Croneck plants, and zinc ore to the former Uthemann smelter). The remaining ore was sent to plants in: Brzeziny Śląskie, Piekary Śląskie (Zakłady Górniczo-Hutnicze im. Ludwika Waryński), Bolesław (ZGH Bolesław), Trzebinia (Zakłady Górnicze Chrzanów), Wełnowiec (formerly Hohenlohehütte), and also in small quantities to the zinc smelter in Radzionków (formerly Lazyhütte). Marcasite was sent to paper mills in Gdańsk, Gryfów Śląski and Włocławek. In 1961, Zakłady Górnicze Marchlewski was incorporated into Zakłady Górniczo-Hutnicze Orzeł Biały. In 1969, the mechanical processing plant at the mine was modernized, and “Disa” type concentrators were used. In the 1970s, as a result of the gradual depletion of deposits, the volume of extraction in the mines of the Orzeł Biały combine began to decline; in 1976 the processing plant at the Nowy Dwór Mining Plant was closed, and therefore the ore from the area of ​​this mine (exploitation ended in 1979) was extracted through the Chrobry shaft. Mining in the area of ​​the former Marchlewski mine was ended in December 1981 (according to another source, it was carried out until 1985). #blogodkrywcy #bytom #mines #urbex #ruins #monuments #technicalmonuments #industriada #adventure #mysteriousworldofruins #musicfordestruction #mine #minecynkubytom
