FLOTATION DEVICE, METHOD FOR OPERATING THE FLOTATION DEVICE AND USE THEREOF

摘要

A flotation device for separating off a valuable mineral from a suspension, has a housing having a flotation chamber, a foam collector for removing a foam product formed in an upper region of the flotation chamber, a feed arrangement for feeding gas and/or suspension into the flotation chamber, an adjustable orifice via which the flotation chamber is horizontally divided into an upper part and a lower part and an open internal diameter of the flotation chamber is locally avoidable. The orifice is arranged completely in a suspension region of the flotation chamber. A measuring arrangement determines a variable in the operation of the flotation device. A control appliance connected to the arrangement automatically adjusts the orifice in dependence on the at least one state variable.
