SPECIAL FEATURE

Smelter It is proposed that a smelter be built to treat zinc concentrate produced at Gamsberg. The zinc concentrate produced at the existing concentrator plant will be treated in the smelter using the conventional roast-leachelectrowinning (R-L-E) process. The full process would involve the treatment of 680 000/tpa of zinc concentrate to produce 300 000/tpa of high-grade zinc ingots for export. As a by-product 450 000/tpa of 98.5% pure sulphuric acid will be produced for both export and consumption within South Africa*. Various types of infrastructure will be needed to support the smelter. These include: • Secured landfill facility: 21ha in extent and situated 1km away from the smelter, connected by a paved road. • New water pipeline: Approximately 7km water pipeline to connect the Horseshoe reservoir with the smelter complex.

• B  usiness partner camp: 12ha for accommo-dation during the construction period. • L aydown area: 15ha for use during the construction period. • Upgrade of transmission line: upgrade 66kV transmission line to 132kV transmission line within the existing servitude and associated upgrades to the Eskom substation at Aggeneys. In 2018 alone, Vedanta spent R44-million on skills development, health, enterprise development and municipal infrastructure support, with a further R77.5-million spent with local businesses. In the period 2014 – 2019, Vedanta over R77 million on a range of CSR programs, and over R88 million on various training initiatives. Gamsberg is considered one of the most digitally advanced mines in South Africa, which will give impetus to the provincial ICT sector.

Downstream investment Non-ferrous metals such as zinc have characteristics that make them immensely useful in a wide range of downstream applications. Resistance to corrosion and their non-magnetic qualities are among the reasons for the wide range of uses to which they can be put. It is envisaged that investors wanting to take advantage of the by-products of the mine and the smelter will be attracted to the Namakwa SEZ. Various wastes and by-products will be generated by the smelter that could be useful to investors. Waste includes: Iron cake stabilized (dry), Jarofix; effluent treatment plant cake (dry); evaporation pond salts (dry); and cellhouse sludge (dry). By-products include: manganese cake (dry); Cu-Cd cement (dry); Co-Ni cement (dry); and sulphuric acid (wet). Investors in this category include businesses in the follow sectors:
