Chromite: The only mineral ore of chromium metal
Podiform deposits are known in Kazakhstan, Russia, the Philippines, Zimbabwe, Cyprus, and Greece. The first discoveries of podiform chromite deposits were made near Baltimore, Maryland in the early 1800s. These deposits supplied nearly all of the worlds chromite until about 1850. These deposits were small and are no longer in production.
