As is seen in Figure 1, potassium dichromate, K2Cr207, is red, potassium chromate, K2Cr04, is yellow, and chromium trichloride, CrCl:), is green. The element (1) is found in the combined fom mainly as the chromite ore, FeCr204, a spinel. Here chromium occupies .octahedral sites and Fe occupies tetrahedral sites. Lower abundant ores are crocoite (PbCrOJ, chrome ochre (C1-20:3)a, nd chromium in trace am0unt.s is found in emerald and ruby. The main deposits are in southern Africa with 96% of the known reserves.
