Chromium is extracted from chromite ore. Chromite is an oxide mineral composed of chromium, iron, and oxygen (FeCr 2 O 4).. Companies in South Africa supply chrome ore from the lower and middle group chromitites of the Bushweld complex and from the upper group chromitite seam (UG2) in addition to platinum group minerals.

For example, the average crustal abundance of chromium is about 0.01 wt %. Chromium ore can sometimes be profitable if it contains 30 wt % chromium. The necessary concentration factor is therefore nearly 3,000 – chromium must be concentrated at least 3,000 times to create profitable ore. ... Figure 9.16 shows an example of gold ore from ...
