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.

An Investigation Into the Adaption of the Induction Furnace for Determining the Equilibrim Diagram of the System Cu2S-FeS

This investigation was started in an effort to find an accurate and efficient method of determining the freezing points of ferrous and cuprous sulphides, mixtures of the two substances, and from this to establish the liquidus line of the equilibrium dia­gram.
