Gamsberg zinc smelter-refinery complex, South Africa – update
Name of the Project
Gamsberg zinc smelter-refinery complex.
Location
Outside Aggeneys, Northern Cape, South Africa.
Project Owner/s
Black Mountain Mining (BMM), a subsidiary of Vedanta Zinc International (VZI), a subsidiary of Vedanta Resources.
Project Description
In 2018, VZI announced that it was considering the development and construction of a zinc smelter-refinery complex to process concentrates from its Gamsberg project at BMM.
Proposed is the construction of a new zinc smelter and associated infrastructure to produce 300 000 t/y of special high-grade zinc metal by processing 680 000 t/y of zinc concentrate.
About 450 000 t/y of pure sulphuric acid will be produced as a by-product and could be exported or used for local consumption.
The smelter is expected to have a 15-year life.
Some of the additional infrastructure required for the smelter project will include a 21 ha secured landfill facility, a 7-km-long water pipeline, upgrades to the transmission line within the existing servitude and an accommodation camp for staff during the construction period.
Potential Job Creation
The project is expected to have a significant positive impact on the Northern Cape, creating jobs – directly and indirectly – and further developmental opportunities in the region.
Net Present Value/Internal Rate of Return

Capital Expenditure
The Gamsberg refinery could result in further investment by Vedanta of between $700-million and $800-million.
Planned Start/End Date
The project has an estimated 36-month construction and commissioning period.
Latest Developments
In September 2020 this year, VZI reported a 104% increase in mineral reserves at the Gamsberg project from 53.7-million tonnes to 109.8-million tonnes.
