Bushveld Complex, South Africa. To say the 66,000 km² Bushveld Complex in South Africa is 'important' is an understatement! It is the world's largest layered mafic intrusion and our primary source of platinum and rhodium. The three key reef-type ore bodies within the Bushveld Complex are the; Merensky Reef – only about 30cm thick but ...

The Impala platinum mine is located in the North West province of South Africa, approximately 25km north-west of Rustenburg and 140km west of Pretoria. The project is a 10-shaft mining complex covering a total area of approximately 250km 2 . The Impala platinum mine exploits the Merensky and UG2 Reefs of the Bushveld Igneous Complex.
The Bushveld Igneous Complex (BIC) is known for its laterally extensive platinum group element–bearing layers, the most famous being the Merensky Reef and the UG-2 chromitite in the eastern and western limbs of the complex. In the northern limb, the Platreef mineralization and a thick chromitite seam below it (referred to as the "UG-2 …
The Bushveld Complex contains the largest reserves of vanadiferous iron ore in the world. The ore is found as plug-like bodies and as seams of magnetitite. The plug-like bodies …
Scientific rationale and sample selection. Here we use the isotopes of iron and oxygen, the two essential elements in magnetite (Fe 3 O 4), on magnetite samples from four major Kiruna-type ore ...
The vanadium ore market is expected to grow to US$3.76 billion in 2027 at a CAGR of 6.1%. The use of vanadium redox flow batteries (VRFB's) for energy storage is an emerging trend market. CRU ...
A genetic link of high-grade iron ore along the southern margin of the Pilbara Craton with magmatic activity triggered by the Bushveld superplume is an exciting …
Resource estimates in the Bushveld Complex are in the range of 337 million tons of oxidized ores, of which two thirds occur in the Platreef ore body. The oxidized ores in the Bushveld Complex contain 819 t of on average 2.4 ppm of the four elements (4E) Pt, Pd, Rh and Au together (Buchholz and Foya, 2015). Platinum-group elements are ...
The Platreef is defined as a series of mafic–ultramafic sills variably mineralised in PGE, Ni and Cu that occur between the footwall and MZ in the northern limb of the Bushveld Complex (Kinnaird et al. 2005).The Platreef is characterised by a more widespread and richer sulphide mineralisation compared with the relatively restricted, …
The shallow mineralised resource of 56.4 million tonnes of ore grading 1.12% V205 is approximately twice the grade of other Vanadium resources that are currently being …
Contained in the titano-magnetite ore is a persistent fractional percentage of vanadium. The total reserves of titanium and vanadium in these iron ores must be very large. It is obvious, therefore, that the ores of the Bushveld igneous complex occupy a prominent place in the world's mineral resources.
1. Introduction. The Bushveld Complex in South Africa is the world's largest reserve of the PGE (Cawthorn, 1999).Two ore horizons are mined in the southern sector, the Merensky Reef and the UG2 (Schouwstra et al., 2000, Scoon, 2009).These differ drastically in their mineralogy, with the Merensky Reef dominated by plagioclase and …
2. Iron Ore Deposits Iron ore deposits are known to occur in sedimentary, hydrothermal, and magmatic environments, but production today is almost entirely from three types of deposit: deposits related to Precambrian banded iron formations provide about 90% of all iron ore mined, and the remainder is derived from metasomatic skarn and magmatic

Abstract. This paper describes several types of mineralization from the upper part of the Bushveld complex as well as the processes leading to their formation. Vanadium and Ti-bearing magnetite layers, which occur throughout the entire Upper Zone of the intrusion, have formed in response to magma mixing events, which resulted either …
Extreme segregation can sometimes produce monomineralic cumulates; a dramatic example occurs in the Bushveld Igneous Complex of South Africa, where cumulus layers of chromite (iron-magnesium-chromium oxide, the only chromium ore mineral) are encased in cumulus layers of anorthite (calcium-rich feldspar).
