Fine coal (− 0.5 mm) is treated in a flotation circuit at Bhelatand washery of Tata Steel. The average ash content of the flotation feed, the fine clean coal, and the tailings of the flotation circuit are 18.5%, 12.5%, and 36%, respectively. The yield of clean coal from the flotation circuit is about 72%. However, the performance of the circuit in …

A critical role of the metallurgist in this system is to define operating limits for the air rate and froth depth of each flotation cell as well as setting sensible mass pull targets for the bank. Optimisation of air and level on individual flotation cells has traditionally been performed by fixing air and changing level or vice versa.
Froth flotation processes are carried out in flotation cells that are grouped into banks, and these banks are interconnected, forming a flotation circuit. A literature …

Optimization of a flotation circuit includes different asp ects, like as, how many cells are required in a bank and how to interconnect banks to obtain the overall optimum perform ance of the circuit.
In copper flotation plants, an increase of 1%í2% in recovery and/or grade is economically remarkable. In this work, reagent optimization is a very important issue, and much time and attention are spent on the optimization of flotation reagents in order to provide the most effective separation and concentration results.
The design of cell-based flotation circuits is often completed in two distinct phases, namely circuit structure identification and equipment sizing selection. While recent literature studies have begun to address the implications of stochastic analysis, industrial practice in flotation circuit design still strongly favors the use of deterministic …
Froth flotation is a complicated process which is difficult to establish its first-principle model. Due to the fluctuations in the grade of raw ore, adaptively adjusting the set-points is extremely important in the flotation process. The inappropriate set-points easily lead to the instability of the process. This paper presents a fuzzy association rule-based …
Most of the observed results show, that for a given flotation system, there is an optimum flotation size range (King, 1982) with lower recovery for the finer and coarser particles, and that the simultaneous optimization of the recovery of these particles in a conventional flotation machine is practically impossible (Schubert and Bischofberger ...

3. Bank recovery is calculated from cell recovery based on feed to each cell. From the first two the relationship between recovery (R) of the two minerals in a single cell is given by: R B = R A / (R A + S 1-R A) where A is the target mineral and S is the relative rate constant (S = k A /k B). To illustrate the third component, bank recovery (R ...
Importantly, the combined effect of changing the chemistry and the hydrodynamics together has been demonstrated. A significant upward shift in the grade-recovery relationship for a cleaner bank was observed. Keywords: flotation optimization, air rate, reagents, frother, froth depth, depressant.
