Abstract
A mixture of oxides, or substances capable of forming oxides under ceramic burning, comprising a difficultly reducible oxide and an easily reducible oxide in relation to a particular reducing agent is subjected to a ceramic burning under oxidizing conditions to produce an exclusively oxidic product, and at least a part of the easily reducible metallic oxide is reduced to metal in solid state by subjecting the oxidic product to the actioon of the reducing agent. The oxide-forming substances specified are carbonates, sulphates, hydroxides, hydrates, and sulphides. The reduction may be effected with carbon monoxide or hydrogen, or solid reducing agents such as carbon or a metal. According to an example, a powdered, briquetted mixture consisting of 5% CaO and 95% Fe2O3 was treated for 24 hours in an atmosphere of oxygen at 1200C DEG ., the treated briquettes appeared to be composed of 60% Fe2O3 and 40% CaO.Fe2O3. The briquettes were then reduced at 1000 DEG C. for 5 hours in an atmosphere of pure carbon monoxide. On X-ray investigation the reduced briquettes were found to comprise the phases Fe and CaO.
