AMIS0392 Cr 51% LYD GX Bushveld South Africa

Origin of Material: This standard was made using LYD GX grade material supplied by Glencore Xstrata plc from the Kroondal Chrome Mine. The mine is situated on the Western Limb of the Bushveld Complex 12km south east of Rustenburg in the North West Province of South Africa.

The source material is a ferrochrome alloy produced from smelting MG1 chromite ore concentrate in a conventional submerged arc smelting operation. From the molten alloy state, this particular sample was granulated – a standard process whereby the molten alloy is rapidly cooled to ambient temperature in a stream of fast moving water

Mineral and Chemical Composition: The alloy has main phases of (Cr,Fe)7C3, (Cr,Fe)23C6, traces(Fe,Cr)3C carbides, Cr containing α-Fe, Cr-Si and traces of S, P, along with minor (<0,5%) amounts of Mn, V, Ti – all species are present in alloy form.

It is not naturally occurring but an artefact of Pyrometallurgical processing of chromite ore to yield ferrochrome alloy and associated oxide slag phase. The sample is from the former.
