CA 2731859

A method of extraction of a metal from an ore or ore concentrate, including the steps of melting a target metal-containing mixture in a heated process vessel at a minimum temperature to form a homogeneous melt in the presence of an appropriate flux material to lower the melting temperature of the target metal- containing mixture, to produce a molten ionic matrix which is largely amorphous and hygroscopic and cooling the matrix.

La présente invention concerne un procédé d'extraction d'un métal à partir d'un minerai ou d'un concentré de minerai, procédé comprenant les étapes consistant à faire fondre un mélange contenant un métal cible dans une cuve de traitement chauffée à une température minimum de façon à former un métal liquide homogène en présence d'un fondant approprié pour abaisser la température de fusion du mélange contenant un métal cible afin de produire une matrice ionique fondue qui est en grande partie amorphe et hygroscopique, puis à refroidir la matrice.
