Magnetic separation is the most efficient separation method of these technologies. Modern magnetic separators are capable of processing up to 500 t ore/h per unit at a very low operating cost (0.3–0.5 kWh power and 2 m 3 recyclable water/t feed ore). Flotation has the advantage of good selectivity, but often it has much higher operating …

Gold Gravity Separation. The gravity separations are simple and separate mineral particles of different specific gravity. As the density of gold mineral is much bigger than gangue mineral, for the gold mine which has gold particles people often use the gravity separation process. Gravity concentration is a proven process for mineral beneficiation.

To accurately answer whether or not gold is magnetic depends on what exactly you mean by "magnetic.". Pure gold, also known as 24k gold, is not magnetic. If you have just purchased a 24k gold bar or ring and it attracts a magnet, you are in trouble because that product isn't pure gold. Other gold types, such as white gold, have a weak ...
