State evaluation is vital to ensure the process operating optimality for copper flotation processes. Specifically, the froth image is the comprehensive embodiment of raw ore properties and process operations, which is one of the key factors to realize condition recognition and state evaluation.
It plays an indispensable role in the mineral beneficiation process; flotation is susceptible to a number of factors during the process, including grinding fineness, slurry concentration, pulp pH, pharmaceutical system, aeration and agitation, flotation time, water quality and other process factors. ... (WMM) presents peer-reviewed original ...
To have a positive control over flotation, it is necessary to be able to determine which and to what degree it is. A cheap way to take this measurement, LITMUS PAPER or a pH METER is used. This is a very important measurement for the flotation operator. Some minerals like Iron pyrite will not float well in an alkaline flotation circuit.
Table 1: Grade/recovery performance of a hypothetical copper ore flotation process. Product % Weight % Cu Assay Feed 100 2.09 Concentrate 10 20.0 Tailings 90 0.1 (a) From Table 1, the Ratio of Concentration can be calculated as F/C = 100/10 = 10. If only assays are available, the ratio of concentration equals (20 – 0.1)/(2.09 – 0.1) = 10 ...
This paper provides a summary of recent studies of flotation froths. The key physical processes operating in the froth are reviewed, and their effect on the behaviour …

Flotation of sulphidic and oxidic copper minerals is reviewed, with particular reference to previous studies of refractory copper ore flotation.
analysis of the flotation reagents to increase the efficiency of the separation process is made, where domestic and foreign approaches to the selection of flotation reagents are given. It should be noted that the combina-tion of primary and secondary collectors is often used in foreign processing plants. Flotation reagents used in
Prediction of metallurgical responses during the flotation process is extremely vital to increase the process efficiency using a proper modeling approach. In this study, two new variants of the recurrent …
The flotation process for the concentration of ores is a method by means of which one or more of the minerals in the ore (usually the valuable ones) are picked up by means of a liquid film and floated at the surface of a mass of fluid pulp. Here they are separated from the other minerals, which remain immersed in the body of the pulp. In …

It is a metallurgical process for the extraction of metals in a pure state from their ores: especially for sulfide ores. Froth flotation is one of the steps which is …
This review aims to offer a comprehensive overview of the importance of frothers in the flotation process focusing on their performance and function in the …
The response methodology and central composite rotatable design (RSM-CCRD) were used for the process modelling and optimization of the flotation process using diesel, methyl isobutyl carbinol (MIBC), and sodium hexametaphosphate as a collector, frother, and depressant to maximize ash reduction, yield, and combustible …

The Flotation Process. Until quite recently copper ore had to be hand-picked if the extraction of the metal was to be economical. In fact, in the last century, ores of 4 percent grade were regarded as almost valueless. Today such ores (which would be regarded as relatively rich in copper) are scarce; the great majority of mines contain the ...
Froth flotation is an important concentration process that can be used to selectively separate hydrophobic materials from hydrophilic waste gangue. In a more …
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. The flotation process was developed on a commercial scale early in the 20th century to
The main factors affecting the flotation process include ore properties (mineral composition, size distribution, particle shape, floatability of minerals, etc.), flotation process (workflow configuration, reagent system, pulp density and temperature, etc.), operating factors, characteristics of flotation machine, etc.
The problem of operational optimization for complex industrial processes is addressed in this paper, and the effectiveness and feasibility of the proposed methods …
The actual flotation process is a complex, multi-factor coupling separation process. The bubble size is synergistically affected by the frother, collector, slurry properties, mechanical energy input, and air flow rate in the flotation cell. The effect of multi-factor coupling on the bubble size should attract sufficient attention.
