  • Frontiers | Formation of secondary hematite and its role

    In some mine tailings, primary sulfides have been completely dissolved and replaced by secondary minerals such as hematite. It seems that formation of hematite is very fast under tropical climate conditions with distinct rainy and dry periods typical for countries such as Zambia and Namibia. Immobilization of contaminants in hematite has implications for other mining sites around the world
