Development of a laboratory method to predict plant flash flotation

The flash flotation circuit on this plant consists of a flash cell and two flash cleaner cells. The flash flotation cell receives its feed directly from the cyclone underflow via a distribution box. The tailings from the flash flotation cell are sent directly to the ball mill feed, and the flash cell concentrate goes to the flash cleaner cells.
