Flotation Circuits. Flotation circuits are typically comprised of rougher, scavenger and cleaner flotation banks. Rougher and scavenger banks are focused on recovery and thus provide maximum residence time. Rougher banks can be large with the number of cells being 5 or greater. Scavenger cells are the last line of defense for avoiding losses.

The flotation rate parameters as regressed in Circuit A were used without modification in this setup. Nine flotation rates were used, for PGMs, chromite and gangue in the roughers, scavengers and cleaning section. The flotation cells were run at different froth depths for this test, as recorded in the published dataset.

In cleaner flotation a minimum of two cells per cleaning stage is recommended in most cases. An exception is the final cleaning stage where one cell is also acceptable. Three cleaner stages is

Column flotation cells, like mechanical cells, are used to perform mineral separations. Column cells do not use mechanical agitation (impellers). ... Cleaner column flotation succeeded in producing final …

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 ...

Cleaner Scavenger flotation bank (9 cells of 160 m3) at CMDIC concentrator. The feed flowrate during the sampling surveys was around 300 t/h, with a Cu grade of 8.7%, P 80 of 55 µm, and a solid content of 15%. Wi th respect to the operating conditions, the first cleaner stage had a more selective operation, with froth heights of …

A flotation bank is a serial arrangement of cells. How to optimally operate a bank remains a challenge. This article reviews three reported strategies: air profiling, mass-pull (froth velocity) profiling and Peak Air Recovery (PAR) profiling. These are all ways of manipulating the recovery profile down a bank, which may be the property being exploited. …

The proposed cleaner circuit design use the Jameson Cell in two separate duties: cleaner/scalper and recleaner (see Figure 2). The cleaner/scalper Jameson Cell …

A single ECS at the "rougher" setting yields 81% recovery when producing a 90 grade zorba product; An RCS System with multi-stage "rougher," "cleaner," "scavenger" processing averaged 98% recovery while …

The MAC flotation cell is mainly used in the flotation section of waste paper deinking pulping, for removal of hydrophobic impurities such as filler, ash, ink particles, etc. It can increase pulp whiteness and meet the requirements of final paper appearance quality. Table 11.11 shows the features of MAC flotation cell.

The use of a gently uprising, aerated fluid greatly reduces the turbulence commonly found in other flotation cells, allowing the effective flotation of coarser particles (Kohmuench et al., 2018). Fluidised bed flotation is advantageous as it can reduce the need for finer grinding, reduce grinding costs, and it accepts feed with very high solid ...

Testwork necessary to define the design parameters for a flotation circuit generally includes: Grindability studies to establish grinding power requirements. Chemical and mineralogical analyses of test composites to establish ore grades, mineral associations and liberation characteristics. Reagent evaluations required for rougher and cleaner ...

The ColumnCell™ is the result of thorough research, proven expertise and two combined legacy technologies. As a tailored solution, the ColumnCell is customizable to suit every customer's individual needs. Superior metallurgical flotation performance for fine ores. High concentrate and froth quality. High availability and high capacity.

Callow-Type flotation cells, with various modifications, have been employed at the Hayden concentrator since 1917. Other flotation machines, such as matless-air and mechanically agitated types, which have been tested in competition, have failed to handle tonnages or give metallurgical results equal to the modified Callow-type cells on the Ray …

Following this, Harbort et al. (1997) estimated the residence time required for mechanical and Jameson cells for cleaner and scavenger flotation circuit at Philex mining corporation to reach equivalent metallurgical performance, which resulted in 30 min and 2.9 min, respectively. The values of mean residence time ...

The Concorde Cell is an enhanced pneumatic high-intensity forced-air flotation type of technology. Unlike agitated flotation, pneumatic flotation involves mixing the air and the pulp in a continuous stream, thereby separating contact and froth treatment zones.
