Froth Flotation Of Gold Crushers Ball Mills And

Froth flotation of gold is a widely used beneficiation method for treating rock gold ore in gold concentrating plant, which is often used to treat gold ore containing sulfide minerals with high floatability. The froth flotation process can concentrate the gold in sulfide minerals to the maximum extent, and the tailings can be directly discarded.

Performance Recognition For Sulphur Flotation Process

As an important indicator of flotation performance, froth texture is believed to be related to operational condition in sulphur flotation process. A novel fault detection method based on froth texture unit distribution TUD is proposed to recognize the fault condition of sulphur flotation in real time. The froth texture unit number is calculated based on texture spectrum, and the probability ...
