Abstract

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.

Claims (2)

1. A method of enhancing an extraction of an element from an ore including the steps of:
a) subjecting the element bearing material to a thermal shock to cause microfracturing of said material without inducing a significant change in a chemical structure of said material and b) processing of the microfractured material to extract said element from said material.
2. The method of claim 1, wherein said thermal shock is provided by microwave energy delivered over a period of time sufficient to cause a heating effect of said material but insufficient to initiate a significant chemical change of said material.
