Mientras que, como se ha visto anteriormente, la reducción indirecia del mineral, necesita una porción de elementos diversos y algunos muy complicados, la reduccion directa se obtiene con elementos bastante sencillos. El procedimiento desarrollado por la Bureau of Mines, despues de ensayos realizados durante mas de tres anos, es de una sencillez verdaderamente rara. Mineral y carbón triturados a un tamatio de 2 a 4 m/m. y mezclados, son tratados en un horno tubular y rotatorio calentado con un gas muy rico en Oxido de carbono o con aceite, donde queda el mineral reducido pero sin llegar a la fusion. La extracción del producto se realiza sin ponerlo en contacto con el aire, y despues de enfriado, se le concentra magneticamente.
