On the Carrying Capacity Limitation in Large Flotation Cells

The results of bubble surface coverage were significantly lower than the expected maximum coverage for the collection zone, indicating that for copper rougher flotation cells it is unlikely to achieve maximum carrying rate at the pulp-froth interface level.

Table of ContentsPhysical Model of FlotationCopper Sulfide FlotationMechanistic Implications of Mechanical Model A physical model of flotation, derived from viewing froth as a kinetic species since it constitutes the carrier of ore particles, not only agrees with and is simulated by engineering math models, but is statistically verified by actual laboratory flotation data. The model couples ...

On the Carrying Capacity Limitation in Large Flotation Cells. 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, 160 and 300 m 3).A model for estimating the carrying rate at the pulp-froth interface as a function of bubble surface coverage, bubble ...

Coarse-particle flotation applied to copper sulfide ores

To overcome these limitations of conventional cells, a new type of flotation cell has recently been developed that works under the fluidized bed principle. With this new cell type, it has been possible to obtain recoveries up to 90% Cu and 89% Mo when a miner al has been floated in the range of 600 µm x

1 Froth Flotation – Fundamental Principles

no flotation can occur. Contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in Figure 5. Figure 5: Simplified schematic of a conventional flotation cell. The rotor draws slurry through the stator and expels it to the sides, creating a suction that draws air down the shaft of the stator.

Industrial flotation cell Gas rate measurementThe overall air flowrate entering the cell was evaluated at the cell air input pipe, of 25 cm diameter, by means of a gas velocity meter. Thus, the radial air velocity profile was directly measured and the overall air flowrate was calculated by integration.

Stem cells: promises versus limitations

The availability of human stem cells not only raises hope for cell replacement therapies, but also provides a system for understanding the mechanisms of embryonic development and disease progression. Nevertheless, it raises ethical concerns that need to be addressed before the use of stem cells in clinical practice.
