PDF PGM Ore Processing at Impala's UG-2 Concentrator

The chrome occurs in the ore as a chrome spinel with iron oxide and only melts at temperatures exceeding 1600deg C. In contrast the furnaces utilized in the platinum industry operate at a much lower temperature of 1400-1500 deg C. Excessive chrome in furnace feeds thus leads to the freezing of the furnaces reducing efficiency and damaging ...

Chromite - Wikipedia

Chromite is a mineral that is an iron chromium oxide.It has a chemical formula of FeCr 2 O 4.It is an oxide mineral belonging to the spinel group.The element magnesium can substitute for iron in variable amounts as it forms a solid solution with magnesiochromite (MgCr 2 O 4). A substitution of the element aluminium can also occur, leading to hercynite (FeAl 2 O 4). ...

chrome ore techniques

The voltammetric analysis has allowed to demonstrate that iron in the sample was as Fe(II). The main compound of the chromite ore was a spinel (magnesiochromite ferroan), identified by XRD from the sample, which constitutes the chromite ore. This technique has also been useful to characterize some silicates as impurities in the chromite ore sample.
