Chromite. Chromium from ores of chromite is used to make essential stainless steel, tool steel, armor-piercing projectiles, and is used in other high-temperature applications. It is a strategic metal to the USA, because since 1961, the U.S has been 100 percent dependent upon other nations for chromium.

Chromite: The Only Mineral Ore Of Chromium Metal

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 world's chromite until about 1850. These deposits were small and are no longer in production.
