The next stage in the chrome plant process flow is ore extraction. There are several methods employed to extract chromite ore from the ground, including surface mining and underground mining. Surface mining involves the removal of soil and overburden to expose the ore, which is then extracted using heavy machinery, such as excavators and loaders.

Alluvial, podiform, and stratiform deposit types are the commercially exploitable chromite ore sources [9,10,11]. Of these deposit types, stratiform-type chromite deposit ores are mainly exploited due to their large lateral continuity and regular layering . The value of chromite ore is however determined by the Cr 2 O 3 content and the Cr/Fe ratio.
