Why Use Gravity Concentration? | Fote Machinery

Why Use Gravity Concentration? | Fote Machinery

Gravity concentration is a process to concentrate the mineral of interest using the difference of specific gravity of gold and gangue minerals. The specific gravity of gold is and the specific gravity of quartz (the common gangue mineral associated with gold) is (, gravity concentration works because gold is heavy, and quartz is light). Gravity causes gold to settle in water ...
