Chromit formel
WebChromitite seams are typically a few millimeters to several centimeters thick and therefore uneconomic for chromium. Instead, the chromitite in the Merensky Reef (Bushveld Complex) is mined as one of the largest PGE deposits on Earth, highlighting the important association between chromitite and PGE mineralization in LMI. WebChromate Chemical Formula The formula of chromate is CrO 42-. The chromate ion usually consists of one chromium atom (+6 oxidation state) and four oxide atoms. The overall charge is -2.
