A method to enhance the extraction of an element from an ore by subjecting the element bearing material to a thermal shock. The thermal shock is sufficient to cause microfracturing of the material without significant change in the chemical structure, thereby reducing or essentially eliminating the refractory nature of the ore. The microfractured material may then be processed in a conventional manner at a relatively higher yield, than would otherwise be the case.
Un procédé pour améliorer l'extraction d'un élément à partir d'un minerai en soumettant le matériau portant l'élément à un choc thermique. Le choc thermique est suffisant pour provoquer la microfracturation du matériau sans changer considérablement la structure chimique, ce qui permet de réduire ou d'éliminer sensiblement la nature réfractaire du minerai. On peut ensuite traiter le matériau microfracturé de manière conventionnelle à un rendement relativement élevé que ce qu'on aurait obtenu autrement.
