Chromite - Wikipedia

Chromium extracted from chromite has been used in anthropogenic processes in the past decades developing major health and environmental concerns around the world. When chromium is in the trivalent (Cr(III)) form, it is a crucial part of a balanced animal and human diet. However, its defect will cause a disruption to the lipids and glucose metabolism in animals and humans. On the other hand, when chromium is in its hexavalent(Cr(VI)) form, it is a highly toxic carcinogen and if ingested by an animal or human it
