separating chromium from chromite

Total Chromium & Hexavalent Chromium Measurement

Chromium (Cr) is the 21th most abundant element in the Earth''s crust, and almost all Cr is from chromite (FeCr 2 O 4) ore.Natural weathering (e.g. rock corrosion) and industrial activities (e.g. leather tanning, stainless steel welding, plating solutions, and Cr pigment production) are common ways Cr is transmitted to our air, water, soil, and food.
