Chromite is hosted in the lower dunite–harzburgite fades (Ali et al. 2017). The ore bodies are generally lenticular and range in size from 10 to 50 m long, 1 to 3 m thick and 30 to l00 m down-dip extensions. The ore is generally massive, compact and consists of chromite spinel, sometimes, ferruginous with minor chrome chlorite and chrome garnet.

Chromite from South Africa is known to be low grade, brittle, and prone to result in fine ore during processing. The average distribution is approximately 75% fine ore, whilst the remainder is classified as lumpy ore [ 19 ].

SYNOPSIS. South African chromite ores are smelted using SiO 2 - and CaO-containing fluxes, normally as quartz and limestone respectively. The purpose of SiO 2 is to lower the melting point of the ore, while CaO is added to ensure that the slag that forms on smelting is fluid enough to enable slag/alloy separation and tapping from the furnace.

Chromite, an oxide of iron, magnesium, aluminum, and chromium, is the only ore mineral of chromium. In nature, chromite deposits are generally of two major types: stratiform (layered) and podiform (pod shaped). Both types are associated with ultramafic igneous rocks. The world's largest stratiform chromite deposits are found in South Africa, in ...

A ~20 kg sample of lumpy 'chromite' ore from South Africa (nominally 95% passing. 100 mm in size) was used in the test work. The lump sample was crushed to.

A characterization study of chromite ore from South Africa was conducted using bulk assays, X-ray diffraction, optical, scanning electron microscopy (SEM), automated electron probe microanalysis (EPMA) and quantitative evaluation of mineral by scanning electron microscopy (QEMSCAN) mineralogical techniques, and quantitative EPMA. The …

Chromium. Chromium (Cr) is a hard, bluish metallic element. The only ore of chromium is the mineral chromite and 99 percent of the world's chromite is found in southern Africa and Zimbabwe. Geologists estimate that there are about 11 billion tons of mineable chromite ore in the world, enough to supply the current demand for hundreds of years.

South Africa holds approximately three-quarters of the world's viable chromite ore resources and dominates the global production of ferrochrome. Albeit completely unintended, small amounts of Cr ...

The chromitites of the Bushveld Complex in South Africa contain vast resources of platinum-group elements (PGE); however, except for the economic upper group (UG)-2 chromitite seam, information on the distribution of the PGE in the ores and on the mineralogical nature, assemblages, and proportions of platinum-group minerals (PGM) is …
