Abstract

Un método para producir polvos de metal por medio de atomización con gas, que comprende al menos los pasos de: a) proporcionar una carga de metal que comprende al menos un material seleccionado del grupo que comprende de residuos de metal, minerales de metal y polvos de metal; b) fundir la carga de metal dentro de un horno de arco eléctrico (106) controlando su composición hasta que se obtenga un baño de metal fundido que tenga una composición deseada; c) derivar el baño de metal fundido del horno de arco eléctrico (106), recolectando este dentro de al menos una cuchara de colada (104); c1) refinar el baño de metal fundido recolectado en la cuchara de colada (104) hasta obtener un baño de metal fundido refinado, donde el paso de refinación c1) es conducido bajo condiciones de atmósfera controlada o vacío o exceso de presión introduciendo la cuchara de colada (104) que contiene el baño de metal fundido derivado del horno de arco eléctrico (106) hacia una cámara de refinación sellable (114), dentro de la cual las condiciones de atmósfera controlada o vacío o exceso de presión son generadas; d) atomizar el baño de metal fundido refinado derivado del horno de arco eléctrico alimentando el baño de metal fundido refinado derivado del horno de arco eléctrico hacia un atomizador de gas, dentro del cual es producido un flujo de baño de metal fundido e impactar el flujo de baño de metal fundido con una corriente de gas inerte de atomización para la atomización del baño de metal fundido en polvos de metal; e) extraer los polvos de metal así obtenidos del atomizador de gas.
