Lubumbashi (formerly official names: Élisabethville (French) and  Elisabethstad  (Dutch)) in the southeastern part of Democratic Republic of the Congo, is the second-largest city in the country, after the capital Kinshasa. Lubumbashi is the mining capital of the Democratic Republic of Congo, acting as a hub for many of the country's biggest mining companies. The copper-mining city serves as the capital of the relatively prosperous Katanga Province, lying near the border with Zambia.
