OneMine | Modelling the Impact of Flash Flotation from Batch Cell
Flash flotation is a process designed to remove coarse, liberated, fast floating minerals from hydrocyclone underflow. Irrespective of liberation, coarse particles would normally remain in a grinding circuit until they are reground fine enough to report to the hydrocyclone overflow. Additionally, minerals of high density also report to hydrocyclone underflow despite …

Abstract - In "La Plata" mine (located in Zacatecas, Mexico), low gold recovery (21±5%) in the flash flotation cell was identified. This also has the consequence that, even when including the flash cell and the complete flotation circuit (rougher, scavenger, and cleaner cells), the global gold recovery does not exceed 78±5%.

The feed to the flash flotation cell comes from a distribution box which splits the cyclone underflow. Typically, one-half to two-thirds of the cyclone underflow stream is diverted into the Flash Cell, with the remainder of the stream returning to the mill feed. Dilution water is also added to the feed to reduce the solids density to ...
