The Democratic Republic of the Congo (DRC) is one of the world’s best-known mineral-rich countries. Its mining industry plays an important role in supplying gold, cobalt, copper, tantalum and diamond to the rest of the world. In addition to having the largest cobalt reserves, the country is also Africa’s biggest copper exporter, producing 1.06 million mt of copper in 2019. Hydrogeek Consulting was tasked to support mining operations in the region through their groundwater modelling expertise. Using FEFLOW, they developed a 3D groundwater model to forecast water inflows to enable more efficient water management decisions.
