The zinc tailings pass over a Table which gives the operator a constant, visual picture of the efficiency of the zinc flotation machine, and also recovers additional zinc values. Zinc concentrates are fed to a Table to remove any lead oxide values which may have floated with the zinc, and then are thickened in a Thickener.
Flotation is the most widely used beneficiation method for fine materials, and almost all ores can be separated by flotation. Another important application is to reduce ash in fine coal and to remove fine pyrite from coal. The flotation machine is mechanical equipment for realizing the froth flotation process and separating target minerals from ore.

1. Introduction. Froth flotation is a process that selectively separates materials by utilizing the differences in their hydrophilic and hydrophobic surface properties (Wills, 2006).Since its introduction to the mining and mineral processing industry at the beginning of the 20th century, it has become the most essential process for recovering …

Selective Flotation: The classifier overflow is treated in a conventional manner using "Sub-A'' Flotation Machines of cell-to-cell design which enables double cleaning of the silver-lead and zinc concentrates without the need of pumps. For large tonnage operations the "Sub – A" Free Flow Machine is optional for roughing and ...
2. Flotation: The finely ground ore slurry is mixed with a flotation agent. The flotation agent type and amount will be selected according to the specific ore properties. Send the slurry into the flotation machine. The gold particles will be adsorbed on the air bubbles due to their unique properties, while other minerals will sink to the bottom.
Conventional feature description methods have large errors in froth features due to the fact that the image during the zinc flotation process of froth flotation is dynamic, and the existing image features rarely have time series information. Based on the conventional froth size distribution characteristics, this paper proposes a size trend core feature (STCF) …
An eight cell "Sub-A" Flotation Machine of the proper size as determined by test is recommended for zinc flotation. This machine provides adequate flexibility for at least two stages of cleaning and also …
La machine de flottation est un dispositif important pour réaliser le processus de flottation. Il peut être utilisé pour traiter des minéraux métalliques ou non métalliques, tels que le cuivre, le plomb-zinc, le lithium, l'antimoine, la fluorine, le talc, etc. Une fois les minéraux soumis à un broyage humide, les minéraux dissociés en monomères sont ajustés en une bouillie …

A novel froth image analysis based production condition recognition method is presented to identify the froth phases under various production conditions. Gabor wavelet transformation is employed to froth image processing firstly due to the ability of Gabor functions in simulating the response of the simple cells in the visual cortex. …
The zinc flotation efficiency and its production index are closely related to the froth velocity which involves significant information about the concentrate grade and mineral recovery. Given the situation that the froth surface is easy to rotate and collapse, of which large deformation cannot be calculated easily, it is difficult to extract the froth …
After lead flotation at optimum pH 8, the flotation of zinc at a different pH (5–11.5), with two collector types, was performed to study the recovery and grade of zinc in the zinc concentrate.
Fig. 2 shows the flowchart of a zinc flotation circuit in a lead–zinc flotation plant. The first rougher is the beginning of the zinc flotation circuit, and its feed comes from the slurry of the lead flotation circuit. After the flotation of the first rougher, its froth flows to cleaner I, II, and III to obtain the zinc concentrate.
Two stages of cleaning and a scavenging machine following the rougher are generally needed in the zinc flotation section (circuit 4, …

Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water. ... Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores.
The small amount of zinc in the ore does not warrant thickening prior to filtration; instead, a filter with sufficient area for filtering the concentrates direct from the flotation machines is used. The zinc and barite concentrates are filtered, using a Disc Filters and the fluorspar by a drum type Fluorspar Filter with stainless steel filter ...
