Very often, during the analysis of rock and ore samples for precious metals, samples are commonly heated at ∼600 °C to volatilize sulfur and oxidize organic matter prior to acid attack, both of which may otherwise co-precipitate the platinum group metals (PGE) and also reduce Au irreversibly to its metallic form [20].

The metallurgical grade chromite used in the production of alloy steel contains 48% Cr 2 O 3. The chemical grade chromite ore with a Cr 2 O 3 content of over 44% can be used in the production of sodium dichromate. Refractory grade chromite has a low (30-40%) Cr 2 O 3 content (Gu and Wills, 1988). There are two groups of chromite de-
