High Chromium Mines

High amounts of chromium are found naturally in two minerals chromite fecr 2 o 4 and crocoite pbcro 4, also known as lead chromate or red lead.Crocoite is a brilliant reddish-orange colored, four-sided crystal mineral that was discovered in 1765 at the beresof mine near ekaterinburg in the ural mountains of siberia.
