wolframite gravity separating gold flotation

17 Flotation of Gold Ores

2 17. Flotation of Gold Ores. also for beneficiation and separation of difficult to treat gold ores. Flotation is also the best method for recovery of gold from base metal ores and gold containing PGM ores. Excluding gravity preconcentration, flotation remains the most cost effective bene ficiation method.

Froth Flotation of Tungsten Ore

The flowsheet consists of three sections: centrifugal separation of low grade slimes, wolframite flotation of gravity concentrates, and magnetic separation of flotation concentrates to upgrade concentrates. Before centrifugal separation, it is necessary to undertake bulk sulfide flotation.

Extracting Tungsten from Wolframite Gold Ore

The classifier overflow passes by gravity to a Super Agitator and Conditioner prior to Sub A Flotation. The object of the flotation section is to remove the remaining fine gold and sulphides before table concentration for the recovery of tungsten.

Scheelite Gravity separation process, flotation process

In the gravity separation stage, Yantai adopts the shaking table to get some or all qualified tungsten concentrate. For the tailings after the gravity separation stage, Yantai floats the scheelite with oleic acid collector, and get 10% 25% gross concentrate, which is sent to wet metallurgical processing.

Examples of flotation reagent schemes for scheelite and ...

The PH value of the wolframite flotation with oleic acid is similar to that of scheelite, and sodium carbonate is used as the adjusting agent. The flotation of wolframite with phenylarsinic acid and phosphonic acid is carried out in acidic medium, and the regulator used is sulfuric acid or hydrochloric acid. Commonly used lead nitrate as activator.
