There is chromite in the black sands of the sea-coast and the banks of the larger rivers.
The principal exports are rubber, sugar, ground-nuts and oil seeds, beeswax, chromite (from Rhodesia), and gold (from Manica).
Important formations of chromite are found at Hagdale and the Heog Hills; steatite occurs at Kleber Geo, and many interesting minerals have been recorded from these islands.
The lining of the crucible may be of either magnesite (MgO) or chromite (FeO Cr203) The whole furnace, electrodes and all, rotates about the line KL for the purpose of pouring out the molten FIG.
Thechromites maybe looked upon as salts of chromium sesquioxide with other basic oxides, the most important being chromite (q.v.).
