UG2 Chromite White Paper S.Africa

UG2 Chromite White Paper (October 2015) Since the depletion of the Merensky reef, more and more South African platinum miners started mining from the UG2 reef. This seam is characterised by high levels of low grade chrome ore (UG2). Traditionally, platinum producers would stockpile this resource as waste material. However rising platinum mining

Mineralogical characterisation of chromite in the UG2 Reef

ENGLISH ABSTRACT: The Bushveld Complex of South Africa contains three of the most important platinum deposits in the world namely the Merensky Reef, the Upper Group Two (UG2) chromitite reef and the Platreef. These three ore bodies are principally beneficiated by froth flotation. During the beneficiation of chromite hosted PGE’s by froth flotation, chromite represents the principal gangue

Beneficiation: an analysis of South African Chrome Ore

UG2 is primarily mined for platinum group of metals (PMG) by the platinum producers and the chrome ore comes out as the by-product of the beneficiation process. UG2 was first mined in 1980, and since then an effort has been made by the South African ferrochrome producers to use of UG2
