Again, this results in a loss of yield
[0020] So far, the flotation process has not reacted adequately to undesired deviations that lead to reduced yields.

Embodiment Construction

[0068] A possible embodiment of the flotation device according to the invention is described below with reference to its application in the mining industry. However, as mentioned above, the flotation device according to the invention can also be used in other technical fields such as the paper industry, the oil sands industry, the waste water industry and in other industries.

[0069] figure 1 Shown is a flotation device 100 which is designed as a pneumatic flotation cell for extracting solid particles from ore minerals. The suspension, referred to here as slurry, comprises, in addition to solid or raw material particles, also particles of gangue to be discarded.

[0070] The flotation device 100 includes a housing 1 . Furthermore, the housing 1 has a flotation chamber 3 for containing the suspension. The flotation cell 3 has an inner wall B on its side facing the suspension or pulp. Furthermore, the vertical central axis M of the flotation device 100 is shown.

Abstract

The invention relates to a flotation device for separating off a valuable mineral from a suspension, comprising a housing having a flotation chamber, at least one foam collector for removing a foam product formed in an upper region of the flotation chamber, at least one feed arrangement for feeding gas and / or suspension into the flotation chamber, at least one 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, and which is arranged completely in a suspension region of the flotation chamber (3), at least one measuring arrangement for determining at least one state variable in the operation of the flotation device, and at least one open-loop and closed-loop control appliance connected to at least one measuring arrangement for automatically adjusting the orifice in dependence on the at least one state variable. The invention further relates to a method for operating such a flotation device and use thereof.

Description

technical field [0001] The invention relates to a flotation device for separating solid particles from a suspension, in particular consisting of valuable minerals, the flotation device comprising: a housing with flotation cells; a froth collector from which the froth product formed in the upper part of the flotation chamber is directed; and at least one conveying device for conveying gas and / or suspension into the flotation chamber. The invention also relates to a device for operating such a flotation device and its use. Background technique [0002] Flotation is a physical separation method for separating fine-grained solid mixtures such as ores and gangues in an aqueous suspension or suspension by means of air bubbles due to the different wettability of the particles contained in the suspension . It is used in the treatment of ore deposits and in the processing of preferably mineral materials with low to moderate contents of active ingredients or raw materials, eg in the...
