The powdered product of grinding the ore is fed into a series of tanks called flotation cells which are filled with a solution containing various oils capable of forming a froth. Air is pumped into each cell, the solution being agitated to bring froth of bubbles to the surface.
In previous study, the selective separation of enargite from complex ore samples in a batch flotation system under controlled pulp potential was investigated (Tayebi-Khorami et al., 2017b).

The paper is about the froth flotation process and its application. It is a metallurgical process for the extraction of metals in a pure state from their ores: especially for sulfide ores.
This phenomenon is shown in Figure 2 for a copper sulfide ore containing primarily chalcopyrite (70%) with some chalcocite and other copper sulfides present (30%) using either potassium amyl xanthate (PAX) collector or a dialkyl thionocarbamate (THC) collector. ... Thus, if one had very ample flotation cell capacity and flotation time was …
Similarly, in a copper or lead ore carrying gold associated with pyrite, it might be profitable to make an iron concentrate containing the gold. ... with the result that such values pass out in the tailing and are lost. In this connexion, the use of a flotation cell in the grinding circuit, as described earlier in the chapter, has been employed ...
The data collected for each individual flotation cell serves as the foundational dataset for creating a virtual flotation cell model, as discussed in the next section. This model considers dependent variables associated with ore kinetics, processing parameters, and cell characteristics, enabling dynamic computation and prediction of …
A new idea was then proposed by combining the advantages of the Reflux Classifier, the Jameson Cell and the HydroFloat, while circumventing their shortages in providing a general solution for flotation.
This paper reviews the literature on the recovery of the above mentioned minerals by flotation. The increasing complexity of ore deposits, declining ore grades and higher global demand for copper ...
Unfortunately, the conventional flotation cell achieves high recovery only in limited size ranges. For example, a sulfide ore might float very well at 90 to 120 microns, but not at 50 or 150 microns.
A better solution may be to use a specially-designed flotation cell known tentatively as second-order flotation (SOF) cell. In this process, microbubbles are generated in a static mixer under highly turbulent conditions.
"The single most important method used for the recovery and upgrading of sulfide ores", that's how G. J. Jameson described the froth flotation process in 1992. And it's true: this process, used in several processing industries, is able to selectively separate hydrophobic from hydrophilic materials, by taking advantage of the different categories …
The Cadia Hill Mine in New South Wales, Australia, which treats a copper-gold ore at the rate of 2100 tonnes per hour, utilizes a 12 m diameter SAG mill (with a 20 MW motor) …
A better solution may be to use a specially-designed flotation cell known tentatively as second-order flotation (SOF) cell. In this process, microbubbles are generated in a static mixer under highly turbulent conditions. A stream of CST is injected into the mixer so that bubble-particle attachment occurs under conditions of high-kinetic …
More ores are treated using froth flotation cells than by any other single machines or process. Non-metallics as well as metallics now being commercially recovered include gold, silver, copper, lead, zinc, iron, manganese, nickel, cobalt, molybdenum, graphite, phosphate, fluorspar, barite, feldspar and coal. Recent flotation research …

Flotation cell is usually composed of tank, aeration-agitation device, froth scraper, pulp discharge valve, and liquid level control mechanism. Flotation operations (roughing, scavenging, and cleaning), usually carried out in single or multiple tanks arranged in series, constitute a flotation system (Fig. 1).

Molybdenite (MoS 2), a valuable by-product of copper ore processing, is first floated with copper sulfides then depressed, to the underflow of a separate flotation cell, by the addition of colloidal dextrin to the pulp feed.
A new method, staged flotation for effectively increasing the recovery of ultra-fine copper oxide ore with a new type of collector (ZH-1, C3-5 carbon chain xanthate) is proposed for the first time. The flotation process and mechanism were examined by flotation tests, entrainment rate analysis, laser particle size experiments and …
