World-class zinc operation in the heart of the Northern Cape

Vedanta Zinc International (VZI) is a grouping of zinc assets located in South Africa and Namibia, owned by the sixth-largest diversified resources company in the world, Vedanta Limited. Vedanta Limited recently invested R5-billion into VZI’s flagship, Gamsberg open-pit and concentrator project in the Northern Cape province, which is now fully operational and was inaugurated in February 2019 by President Cyril Ramaphosa.

VZI’s operations include Black Mountain Mining (Pty) Ltd (consisting of underground operations Deeps and Swartberg as well as the flagship surface operation, Gamsberg Project) located in South Africa’s Northern Cape province, and the Skorpion Zinc Mine and refinery in Namibia’s //Kharas region. VZI’s vision is to create an integrated, world-class regional zinc complex with the values of Safety, Trust, Entrepreneurship, Innovation, Excellence, Integrity, Respect and Care at the core of their business.

As of March 2020, VZI employed more than 4 200 people (including business partners), of which 99% are South Africans: 80% are from the Northern Cape and 60% from the Namakwa District.

ZI’s Gamsberg Phase I open-pit mine represents $400-million worth of investment into South Africa by the Vedanta Group. Life of mine extension at other mines in the complex ($46-million), Gambserg Phase II ($350-million) and a further $850-million worth of investment on a possible Gamsberg Smelter-Refinery Complex are potential future investments in the South African mining sector.

The smelter-refinery is subject to the availability of power and support from government to make the project economically viable.

Leveraging technology

Gamsberg has implemented a unique flotation system, the Staged Flotation Reactors (pictured above). They break the conventional flotation paradigm into individual, optimised reactors which drastically reduce energy and air consumption. The footprint in the plant gets reduced by around 50%, operations become easier and maintenance costs are lower. VZI is the first company in Africa to adopt Staged Floatation Reactors.

Backfilling operations is an integral part of Black Mountain. Underground mining creates voids which need tobe filled. This provides opportunities for mining operations like Black Mountain to dispose of waste material underground and provide support and stability to the surrounding rock mass.

Biodiversity

The Succulent Karoo Biome is unique in its floral diversity. Among the 36 global biodiversity hotspots, the biome is home to at least 6 000 species of plants that have evolved over millennia. VZI’s environmental specialists have worked closely with a wide range of experts, including those from the International Union for Conservation of Nature (IUCN), to ensure the site’s necessary protection, preservation and ultimate restoration.

The Gamsberg Nursery is derived from the Environmental Management Plan (EMP) and the requirements for the Integrated Flora Permit. Since October 2019, there have been 12 000 plants grown with 379 different species. After the upgrade, 129 000 plants will be housed in the nursery.
