final concentrate. The cleaner/scavenger Jameson Cell takes the cleaner Jameson Cell tails plus the reground rougher/scavenger concentrate. The 2Jameson Cell units were sized based on the surface area required to remove 5 t/h/m and not residence time as is the conventional approach. The Jameson Cell can also be simulated from laboratory

 — The concentrator treats 32,000 tpd of copper ore which contains chalcopyrite, native copper and chalcocite. An investigation was under way into the replacement of an existing bank of 15 conventional 300 cubic feet mechanical cells with an alternative, thus freeing them for use as rougher cells in order to increase capacity. It was a requirement ...

A force, many times greater than the normal gravitational pull, is exerted by this means on particles in the film flowing across the surface. This enhances the separation process to a great extent. MGS in close circuit with lead rougher cells of graphite schist-hosted sulfide ore improves the lead concentrate metallurgy from 20 to +40% Pb.

 — Prior to compositing the individual downbank rougher and scavenger cell products, for modal analysis, the metal distribution by flotation cell products was determined. It was apparent from this analysis that most of the lead, presumably as liberated galena in the ore, was recovered in the scavenger circuit.

The role of flotation columns in comparison with conventional mechanical flotation cells is discussed under the scenario of Brazilian flotation technology. All iron ore concentrator circuits commissioned since 1990 incorporated column only flotation technology in rougher, cleaner, scavenger configuration. Columns were also added to existing circuits, …

is left in the tailings. The antimony flotation circuit consists of the following stages: roughing, scavenging I, scavenging II, cleaning I and cleaning II, as shown in Figure 1. In the stibnite flotation process, the ore pulp from upstream process firstly comes into the first cell of the rougher, and then

A large sulfide copper ore concentrator, commissioned in 2004, utilises large size tank cells (20 cells of 160 m 3 ) in the rougher and scavenger of the cleaner tailings stages and columns

 — 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 ...

 — The ore is mined from an open pit, crushed, and fed to ten ball mills. The concentrator is divided into two parallel comminution-flotation sections, so that five ball mills feed each flotation section. Both sections consist of three bulk copper and molybdenum rougher flotation lines, and the rougher concentrate is transferred to a regrinding stage.

ABSTRACT. The operational proof-of-concept for the flotation cell class of 500 m3 and larger is discussed in this paper. Two different sites are used as case studies and …

cell are six TankCell e160 Cu rougher-scavenger cells. M attsson . et al, 2015a provides a more detail description of the K evitsa circuit. After the start-up of the e500 cellhydrodynamic and metallurgical performance was studied, in detail. As part of this, the cell was operated at different mixing speeds and slurry samples

 — The ground ore is then concentrated in a Falcon centrifugal concentrator with concentrate being processed by amalgamation process. Gravity tails are sent to a flotation circuit where the copper ...

 — In the concentrators described here, however, the arsenic problem is not serious enough to warrant installation of special arsenic separation circuits. Dominion Explorer INC, Canada The type of ore processed here is mostly stibnite but also contains a small proportion of native antimony. The ore grades between 2% and 10% Sb, …

 — As shown, the standard rougher-cleaner (Circuit 2) and rougher-scavenger (Circuit 3) configurations each have efficiencies 1.33 times greater than the single-stage process. Note that the rougher-scavenger-cleaner (Circuit 4) configuration incorporating three stages has an efficiency that is twice that of the single-stage process.

 — All iron ore concentrator circuits commissioned since 1990 incorporated column only flotation technology in rougher, cleaner, scavenger configuration. Columns were also added to existing circuits ...

 — Open pit mining is generally employed with trucks or train haulage of ore to the nearby concentrator. However, there are a few underground mines using block caving methods. ... Occasionally the …

 — The rougher flotation froth of cinnabar passes to the cleaner cell,while the scavenger froth is returned to the first rougher cell. This arrangement, including re-circulation of the cleaner tailing, is accomplished without the use of pumps, a typical illustration of the great flexibility of the "Sub-A" Flotation Machine.

 — New feed rate is presently 370 tons per hour of minus 3/8 in ore. The flotation circuit consists of 6 rougher rows of 14 cells each of 300 cubic foot Wemco flotation cells. The cleaners are two rows of 14 cells each of 300 cubic foot Wemco cells. The flotation cell are divided into two sections each fed by 3 ball mills through a Denver …

 — Jameson cells are also used for prefoliation to remove naturally hydrophobic gangue materials (e.g., talc, and carbon) from the concentrates (Pokrajcic et al., 2005). When the amount of fast-floating material is significant, these cells can also be used for rougher-scalper and roughing duties to produce a high-grade concentrate (Curry et al ...
