Abstract
A method of sorting mined material for subsequent processing to recover valuable material, such as valuable metals, from the mined material is disclosed. The method includes a combination of selective breakage of mined material, for example, by using microwaves and/or high pressure grinding rolls, subsequent size separation, and then particle sorting of a coarse fraction of the separated material based on differential heating and thermal imaging.
