简介 |
A method and system for separating valuable material, such as precious metals and rare earth elements, from a raw material, such as coal, is disclosed. The system may include a crusher or pulverizer for producing finely crushed material. This crushed material may be made into a slurry and placed into an econosizer for separating material by its specific gravity. High specific gravity material may be further refined using magnets, separators, or centrifuges, among other disclosed components of the system. |
