Kryvbas

Kryvyi Rih Iron Ore Basin (Ukrainian: Криворізький залізорудний басейн, romanized: Kryvorizkyi zalizorudnyi besein; Russian: Криворожский железорудный бассейн), commonly known by the portmanteau Kryvbas (Ukrainian: Кривбас; Russian: Кривбасс, romanized: Krivbass) is an important economic and historical region stretched between central and southern Ukraine around the city of Kryvyi Rih, specializing in iron ore mining, steel industry and some uranium ore[1] mining in the past 20th century.

[citation needed] Named after the city of Kryvyi Rih, the basin occupies the western part of the Dnipropetrovsk Oblast, as well as some small parts of the neighboring Kirovohrad and Mykolaiv oblasts,[2] in a valley of Inhulets and Saksahan rivers (both are tributaries of the Dnipro).

With the exception of AMKR, owned by ArcelorMittal, the steel companies of the region are controlled by either Rudomain LLC or Metinvest.

A major beneficiation works Kryvyi Rih Mining and Processing Plant of Oxidized Ores (KRMPPOO) (Ukrainian: Криворізький гірничо-збагачувальний комбінат окиснених руд, romanized: KGZKOR) was under construction in the early 21st century in the neighboring town of Dolynska (Kirovohrad Oblast).

In January 2022 it was announced that locally based company Rudomain LLC acquired the Ukraine-owned share in the project.
