The Chromite Deposits of the Great Dyke — Rhodesia
Over five hundred kiolmetres long and rarely more than ten wide, it traverses the Archean Shield of Zimbabwe (Rhodesia) from north to south. Within layered ultrabasic rocks are several seams of chromite. These are strikingly persistent and together constitute the world’s largest resource of that Mineral.

Chromite - an overview ScienceDirect Topics
The most important historic sources of chromite from podiform deposits are in Kazakhstan, Turkey, and Albania (Papp and Lipin, 2001a,b; Papp, 2010). Zimbabwe is the only country to exploit both stratiform and podiform deposits (Fig. 11.2). Mining of chromite is carried out by open-pit and underground mining.

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.
