The Application of a Laboratory Induction Furnace to the Selective Smelting of a Montana Chromite Concentrate

The purpose of this experimental work was to determine with the utilization of a laboratory sized induction furnace a method whereby a high-iron Montana chromite concentrate could be successfully smelted to yield a product suitable for the subsequent production of standard ferrochrome.

Induction Furnace Smelting of Montana Chromite

In 1939 the total world production of crude chromite was approximately 1,167,000 metric tons; of which the United States produced only 3,672 metric tons and imported over 317,500 metric tons. Imports came mostly from the Philippine Islands, Cuba, South Africa, and Rhodesia.
