Development and Expansion of the Langer Heinrich Operation in Namibia

Abstract

The Langer Heinrich Uranium Mine (LHU) is located in the west of central Namibia, Southern Africa. It lies 80 km east of the major deepwater port at Walvis Bay and the coastal town of Swakopmund. Designed to produce 2.6Mlb/a U{sub 3}O{sub 8}, LHU was the first conventional mining and processing operation to be brought into production in over a decade. The construction and staged commissioning of the project was successfully achieved on 28 December 2006 and the mine was officially opened by the President of Namibia on the 14{sup th} March 2007. The ramp up to nameplate production was hampered early on by some mechanical and process issues all of which required technical solutions to be developed. With these in place, production now exceeds nameplate and lessons learnt have been incorporated into an expansion to 3.7 Mlb/a currently nearing completion. Further expansion options are also being evaluated and a number of innovative flowsheet developments are under consideration, driven by a recent, large increase in the proven reserves. This paper tracks the development of the LHU operation focusing largely on the metallurgical processes employed, some lessons learnt and some considerations for the future. (author)
