  • UG2 Chromite Ore Study - Core Consultants Group

    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

  • THE FLOTATION OF SOUTH AFRICAN CHROMITE ORES

    2014-5-14  South Africa is the largest producer of chromite ores, where over 70 % of world chromite ore reserves are believed to be located. Today, South Africa supplies approximately 50 % of world's supplies of chromite ores. So, it is the leading producer of chromite ore and concentrate globally and a major supplier of ferrochrome.

  • The Impact of Platinum Production from UG2 Ore on ...

    2010-1-5  South Africa’s BIC chromite seams are relatively low grade with Cr/Fe ratios of typically 1.7 or less. Early producers exploited reserves with Cr/Fe ratios of >3, but following ... although use of UG2 for South African charge chrome production is on the upswing.

  • Mineralogical characterisation of chromite in the UG2

    During the beneficiation of chromite hosted PGE’s by froth flotation, chromite represents the principal gangue mineral. This is particularly true for the UG2 main seam. An excess of more than 3% in mass of chromite in the PGM concentrate is known to result in significant problems in the downstream processing and extraction of PGEs.

    2009-8-27  Flotation performance was evaluated using the relationship of mass to water recovery as well as the chromite recovery. Experimental details The ore The UG2 ore was obtained from the Bushveld Igneous complex in the North West province of South Africa. The UG2 ore consists mainly of chromite at a composition of roughly 26% by mass.

    IntroductionBushveld ChromititesThe UG2 PyroxeniteThe E Unit pyroxenite, Lower Critical ZonePetrogenesisConclusionsAcknowledgementsStratiform chromitites are common features of large, layered intrusions. Most mechanisms proposed to account for the chromitites involve changes in chemical or physical conditions that cause the magma to become supersaturated in chromite and remove other phases from the liquidus, thus inducing chromite to crystallize and accumulate in monomineralic layers on the magma chamber floor. Among the proposed changes are increases in total pressure (Cameron, 1977; Lipin, 1993), fO2 (Cameron Desboro...
