Batch flotation tests have indicated that for certain minerals the flotation characteristics in the cleaner tests are substantially different from those in rougher tests conducted under the same conditions of pulp level, impeller speed, aeration rate and froth removal. The differences are most pronounced for the coarse particles.

Flotation Circuits for Air-Lift and Pneumatic Cells. An air-lift machine can often be run as a rougher-cleaner cell, as in circuit No. 5 (Fig. 52), by taking a finished concentrate off the first few feet and returning the froth from the rest of the machine to the feed end. This method is also applicable to pneumatic cells, but its use is not ...

Introduction. The two circuits in question are shown in Fig. 1. Both are rougher-cleaner-cleaner/scavenger circuits (R-C-CS), one designated open (R-C-CS (o)) as CS tails are sent to final tails, the other closed (R-C-CS (c)) as CS tails are recycled to the rougher. Both circuits are in use, North American Cu/Mo plants often employing R-C …

For more information and a review of the test's data points, contact ...

For modelling, scale-up and analysis purposes, two zones are distinguished in the flotation cell: (a) the collection zone, where the particle-bubble aggregate is formed and carried to the pulp–froth interface (true flotation) and (b) the cleaning zone (froth), located between the pulp–froth interface and the concentrate overflow, where ...

Rougher flotation. Cleaning flotation. Tailings re-treatment. Ofloading overloaded flotation circuits. "A single, full-scale REFLUX Flotation Cell is anticipated to provide an economical solution for industry to efectively replace ten flotation cells with a single unit, to rapidly recover valuable particles into a slurry concentrate.

The 2nd cleaner offers 2.5 Minutes of Measured flotation time; The 1st cleaner offers 7 Minutes of Measured flotation time; The Rougher/Scavenger bank offers 12.5 Minutes of retention time.** One might argue that because the Scavenger Conc must be refloated in the Rougher cells, the circuit provides only 7 minutes (5 cells/9 cells X …

Reagent evaluations required for rougher and cleaner flotation, including: o slurry pH. o collector dosages and types. o mineral depressants and activators. o frothers. Rougher flotation grind-size versus recovery, including flotation of timed concentrates to evaluate flotation retention time requirements.

World's best flotation performance The industry-leading TankCell range provides the world's best flotation performance and has the widest range of cell sizes on the market, from 5 to 630 m³. Our cells provide superior performance across all duties in rougher, scavenger and cleaner circuits. Based on in-depth test work, we can design

dramatic reduction from 33 to 5 flotation cells. The new cleaner circuit consists of one B5400/18 cleaner/scalper Jameson Cell, one B5400/18 recleaner Jameson Cell and three cleaner/scavengers (one B5400/18 Jameson Cell and the two 100 m3 Wemco). The cleaner/scalper Jameson Cell takes rougher concentrate and produces final concentrate.

The first cleaner concentrate goes to the second cleaner circuit consisting of eight parallel flotation columns, each 4.5 m in diameter and 13.5 m in height. 1.2. Large size flotation cells. Mechanical cells in the rougher flotation circuit are self-aerated, cylindrical in shape and are 6.8 m in diameter and 4.4 m in height giving a total ...

The rougher cell has dimensions of 3.37 m × 2.6 m so the froth covers much more lateral distance comparatively; as a result the froth residence time is expected to be much longer for the rougher cell than the FDB device. This could lead to more effective drainage of entrained particles and consequently improvement of the rougher …

The rougher flotation stage under study is composed of 5 banks, the first one consists only of one tank cell whereas the others consist of two, as shown in Fig. 1. Download : Download full-size image; Fig. 1. Sampling points in a rougher flotation circuit used for the validation of the proposed model.

Mineral carrying rates across the pulp-froth interface in the range of 1.4-3.2 tph/m 2 and bubble surface coverage between 7 and 22 %, have been determined in large rougher flotation cells (100 ...

Jameson Cell has accurate scale-up reliability and is the real-word specification in any and all duties within a flotation circuit: rougher and scavenger duty; cleaner and cleaner scavenger duty. In fact, a single Jameson Cell has successfully replaced a traditional circuit of cells; and unlike other competing cells, it has no moving parts.

Flotation circuits use multiple flotation cells in series to recover the maximum amount of desired minerals. Circuits consist of a set of cells called rougher, cleaner, and scavenger, as illustrated in Figure 5. Rougher flotation cells are usually mechanical type and appear first in the circuit, to increase the recovery of the valuable …
