CA 2448958

A method for the direct preparation of metal from metal-containing material comprising providing metal-containing material and a reducing agent, mixing the metal-containing material with the reducing agent to form a mixture charging the mixure by an appropriate method except flowing a stream of small particles into a container, heating the mixture with minimal contamination by applying microwave energy to the mixture until molten metal is released from the metal-containing material, accumulating the molten metal by gravity at the bottom of the container, and discharging the metal from the container.

L'invention concerne un procédé permettant de préparer directement un métal à partir d'une matière contenant du métal. Ledit procédé consiste à fournir une matière contenant du métal et un agent de réduction; à mélanger la matière contenant du métal et l'agent de réduction afin de former un mélange; à charger ledit mélange (à l'exception d'un flux de petites particules) dans un récipient à l'aide d'un procédé approprié; à chauffer ce mélange avec contamination minimale par application d'une énergie microonde sur ledit mélange jusqu'à ce que le métal fondu soit libéré de la matière contenant le métal, à accumuler le métal fondu par gravité au niveau du fond du récipient; et à décharger le métal du récipient.
