Abstract
L'invention concerne un procédé permettant d'améliorer l'extraction d'un élément d'un minerai. Ce procédé consiste à soumettre le minerai ou un matériau portant l'élément à des rayons électromagnétiques pour induire la pyrolyse du matériau. Le résidu de pyrolyse peut ensuite être traité de manière classique pour extraire l'élément. Les rayons utilisés dans l'invention ont une longueur d'onde qui est supérieure à celle des rayons de micro-ondes et qui est, de préférence, égale à 100 mm minimum. Les ondes radio sont, de préférence, utilisées comme rayons pour effectuer la pyrolyse.
