RE:RE:RE:RE:RE:Not raining on anyone’s parade, but.....Agreed, I’m not an expert by any means but from what I understand the sorter uses x-ray to sort the parent material from the minerals by density. I can only assume that the mineralized materials are then further separated during the smelting process as there are a number of chemical and mechanical methods to achieve that. I might be way off, but I’m willing to learn something here if somebody has more information to add.
