A process for producing chromium iron alloys suitable for steel making directly from chromite ore wherein fines of chromite ore with additions of carbon fines, and accelerant and a binder are agglomerated and the dry agglomerates are fed into a reaction vessel with natural gas as a reducing agent at elevated temperatures adequate for reduction for thereby producing a chromium iron alloy suitable for steel making. The preferred accelerant is an alkali in the form of an oxide, hydroxide or carbonate, sodium hydroxide being preferred.

A process for producing low carbon chromium iron alloys directly from chromite concentrates wherein superheated liquid aluminum is flowed in a controlled manner into a reaction vessel preheated to a temperature of approximately 1,000 C. while simultaneously feeding chromite concentrates preheated to a temperature in the same range at a controlled rate into the preheated reaction vessel. The ratio of chromite to aluminum is controlled to be at or above the stoichiometric ratio required to reduce the oxide from chromium and iron to low carbon ferrochrome alloy. Burnt lime is continuously added to the vessel in an amount sufficient to form and flux a slag of the eutectic composition known as calcium aluminate.
