The conventional flotation circuit utilises both forced air and self-aspirated cells and employs two stages of cleaning. This is broadly depicted in the flow sheet of Fig. 2.The combined re-cleaner concentrate is directed to final concentrate, whilst the 'Scavenger 8 Tail' is the final tails from the flotation circuit, which is directed to the …

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 …

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 …

The conditioned pulp goes to Cell No. 1 of the "Sub-A" Rougher Flotation Machine. With the "Sub-A" it is often possible to remove a substantial amount of molybdenum concentrate of high enough grade to require no further cleaning. The remainder of the rougher concentrate normally requires conventional multiple cleaning.
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.
The selection of flotation cells can depend on residence time, froth carry rate and concentrate lip loading. In order to minimise capital and operating costs, there are different launder configurations available, depending on the froth carry rate and concentrate lip loading requirements. Different sections of the circuit, such as the roughers ...
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 objective of the section is to recover the bulk of the PGM minerals in the feed, into a much smaller mass of concentrate. The concentrate from the rougher section is fed to the cleaner flotation section. The tail is the material that leaves the bank of flotation cells once it has passed through the flotation process (waste material).

The flotation circuit at Andina Division is comprised of three lines of rougher flotation (lines A, B and E). The rougher concentrate is sent to a regrinding step in vertical mills. Subsequently reground concentrate is sent to 6 columns cells (1 stand by) producing the final concentrate. Tailings from the column cells are sent to a scavenger stage.

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 operating parameters of cleaner flotation tests were the same to those of rougher flotation tests. In each cleaner flotation test, the rougher flotation concentrate was poured into the cell and was agitated for 1 min at an impeller rotation speed of 1800 rpm. No flotation reagents were added to the pulp.
Froth washing is also widely used in cleaner stages of flotation cells [29,83, 84]. However, little application has been reported in scavenger cells, which contain the largest amounts of gangue ...
