Conflict Minerals 101: Tin, Tungsten, Tantalum, and Gold
Sep 26, 2014· Tin Tantalum Tungsten Gold; Often used to coat other metals to prevent their corrosion and to create alloys Stores electricity and is used in alloys for its strength Commonly used in tools, cell phones, and hightemperature situations, also used in alloys for its strength Malleable, not highly corrosive, and highly conducive to electricityThe physical properties (specific gravity, magnetic and electrostatic response) listed above are used to concentrate and separate these minerals using gravity separation, magnetic separation and electrostatic separation respectively to a saleable product or as a feedstock for further processing As tantalum, tin and tungsten deposits areTANTALUM, TIN AND TUNGSTEN
