Utilisation of lower grade (Jigging technology has progressed to a point where SishenÆs 50 to 60 per cent Fe run of mine (ROM) material, once considered as waste, can be beneficiated to produce a saleable 64 per cent Fe product. This has been confirmed through appropriate beneficiation testwork. Consequently, Sishen can now produce saleable product from material not currently included in the resource definition, significantly increasing the resource base of the mine and ensuring higher resource utilisation. Mine planning utilised the geological models to produce detailed planning schedules, reflecting the current and SEP plants separately, optimised to comply with product specifications of both the current and SEP plants and to confirm the viability of the low-grade resources identified as SEP feed material. The SEP product specifications have been derived by optimally matching iron ore market requirements with the revised resource base. A 64.0 per cent Fe lump product and a 63.5 per cent Fe fine product are the optimal SEP products. The SEP plant will be able to produce 10 Mtpa at an average yield of 60 per cent and a lump to fine ratio of 62:38. The plant consists of five major sections: namely crushing, material preparation, beneficiation, final product handling and quality control services. Maximum integration with the current Sishen plant was considered. Kumba currently has an agreement with Transnet to rail up to 23.5 Mtpa through the Sishen Saldanha iron ore export channel (IOEC). Transnet and Sishen Iron Ore Company have signed a Definitive Agreement that deals with the expansion of IOECÆs capacity, which increases KumbaÆs entitlement from 23.5 Mtpa to 35.0 Mtpa. The detailed enviro-legal impact assessments for the SEP indicated that the project has low enviro-legal risk as a result of it being a brownfields project incorporated into the current Sishen operations.
