Abstract

Un procedimiento de fundicion directa basado en un bano fundido para producir metales a partir de oxidos metálicos (incluyendo oxidos metálicosparcialmente reducidos). El procedimiento incluye provocar el movimiento ascendente de salpicaduras, gotasy corrientes de material fundido de una capa demetal (15) del bano fundido que: (i) promueve un fuerte mezclado de metal en una capa de escoria (16) del bano fundido de modo que la capa de escoria (16) semantiene en una condicion fuertementereductor a llevando a niveles de FeO inferiores a 8% en peso basado en el peso total de la escoria en la capa de escoria(16), y (ii) se extiende en un espacio por encima de una superficie inactiva nominal del bano fundido para formar una zona detransicion (2 3).
