  • Froth flotation - Wikipedia

    Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

    Take, for example, the introduction of column cells, which at the time was considered revolutionary. Today, column cell technology is widely used throughout the industry. Or the continuing trend toward larger and larger flotation units, as concentrators are designed for ever-increasing throughputs of lower head-grade ores.

  • An Overview of Optimizing Strategies for Flotation Banks

    The increasing profile represents slowing down flotation in the first cells and re-distributing recovery (mass) down the bank. The corresponding cell-by-cell recovery is not the flat profile from theory but rather trends upwards along the bank. (The profiles probably reveal that cell 5 is over-pulling.)

    Jan 12, 2010  The important thing is to seek advice from those who know flotation intimately, namely your flotation supplier. They can provide potentially easier and more cost-effective solutions. Here, another option would be to customise the launder configuration to a larger froth surface area or lip length, without increasing the number of cells.

  • The increasing use of mixtures of collectors in flotation

    Aug 26, 2013  Increasing use is being made of mixtures of thiol collectors in the flotation of platinum group and sulphide minerals. The use of mixtures is sometimes proposed to produce a synergistic effect, i.e., the flotation performance of the mixture is greater than the weighted sum of the individual contributing collectors.

    Mar 06, 2017  Little is said about selectivity but there is a constant cry for increased recovery. This might be what industry wants but it is certainly not what industry needs. However, physics based studies are merely concerned with increased recovery not increased selectivity; selectivity in flotation is only achieved by attention to the pulp chemistry.
