Abstract
El invento consiste en un proceso para producir magnetita con una pureza no menor al 90%, y superando el 98%, por oxidación de wüstita (óxido de hierro) pulverizada, bajo temperaturas desde los 200 °C hasta los 800 °C, con introducción de agua líquida o en forma de vapor, a contracorriente o en forma concurrente, en un reactor con atmósfera controlada calentado externamente. La cantidad de agua utilizada para oxidar la wüstita es de 60 a 500 ml por kilogramo de wüstita. Los granos de polvo de wüstita introducidos al reactor tienen un tamaño no mayor de 100 µm.
