Advantages Of Using Gravity Concentration For Gold
Gravity concentration has a lower overall cost per ounce produced compared to cyanide leaching and froth flotation. Not only is the equipment cheaper to purchase, it’s also less expensive to run on a day-to-day basis. Froth flotation and cyanide leaching both require costly reagents for optimal gold recovery.

Publisher Summary This chapter presents the principle of gravity concentration, its methods, and types. Gravity concentration methods separate minerals of different specific gravity by their relative movement in response to gravity and one or more other forces, the latter is often the resistance to motion offered by a viscous fluid such as water or air. It is
