ShapshotThe Sylvania Dump Operations (SDO) comprises six chrome beneficiation and PGM processing plants: Millsell, Mooinooi, Lesedi, Doornbosch, Lannex and Tweefontein, focusing on the retreatment of PGM-rich chrome tailings materials from mines in the Bushveld Igneous Complex. The SDO is the largest PGM producer from chrome tailings re-treatment in the industry.

Summary:

Sylvania Dump Operations treat PGM-rich chrome tailings materials from Samancor Chrome’s mines on the Western and Eastern Limbs of the Bushveld Igneous Complex.

Sylvania Dump Operations (SDO) are treating beneficiation and platinum group metal processing plants: Millsell, Mooinooi, Lesedi, Doornbosch, Lannex and Tweefontein, focusing on the retreatment of PGM-rich chrome tailings materials from Samancor Chrome’s mines on the Western and Eastern Limbs of the Bushveld Igneous Complex.

The Bushveld Igneous Complex (BIC) is situated within the north-central Kaapvaal Craton, this complex is a saucer-like intrusive igneous mass extending for about 400 km from east to west and roughly the same distance north to south.

This massive Proterozoic intrusive body, or, more likely, a series of interconnected intrusive, has a surface area of approximately 66 000 km2 and consists of a mafic-ultramafic succession of layered and massive rocks known as the Rustenburg Layered Suite (RLS), a penecontemporaneous series of granitic rocks, termed the Lebowa Granite Suite and felsic extrusive rocks of the Rooiberg Group. For the majority of the area of the BIC, the Transvaal Supergroup forms the floor.

The lower mafic layered intrusion, the Rustenburg Layered Suite consists stratigraphically of a Marginal Zone, a Lower Zone, a Critical Zone and an Upper Zone.

Economic concentrations of PGMs occur mainly in three distinct units within the Critical Zone: Merensky Reef; Upper Group 2 (UG2) chromitite; and Platreef. The Merensky Reef and UG2 Reef occur around the Eastern and Western Limbs of the complex, while the Platreef is found only along the eastern edge of the Northern Limb.

The Merensky and UG2 reefs are narrow tabular orebodies that extend laterally over hundreds of square kilometres, resulting in extensive Mineral Resources. Their continuity, established over decades of exploration and mining, allows for the long-range extrapolation of data.

The magmatic layering of the ultramafic-mafic rocks is remarkably consistent and can be traced over several hundreds of kilometres of strike. The layering may be correlated throughout most of the BIC. The dip of the igneous layering is generally shallow and towards the centre of the BIC. The similarity of geology across large areas within each of the three limbs, particularly the sequence of igneous layering that includes both the Merensky Reef and the UG2, is probably indicative of simultaneous differentiation and replenishment of a basaltic magma under essentially identical conditions.
