  • Froth flotation

    The American Institute of Mining Engineers presented Callow the James Douglas Gold Medal in 1926 for his contributions to the field of flotation. By that time, flotation technology was changing, especially with the discovery of the use of xanthates and other reagents, which made the Callow cell and his process obsolete.

  • Optimisation of gold recovery by selective gold flotation for

    Gold flotation is often overlooked as a processing option as the precious metal is viewed as being associated with the sulphide particles present in the ore, even when a proportion of the gold is free. Gold does float readily, however, and the free gold can be selectively floated away from an ore containing sulphides.

    Publisher Summary. In spite of the lack of basic research on flotation of goldbearing ores, the flotation technique is used not only for upgrading of lowgrade gold ore for further treatment, but also for beneficiation and separation of difficulttotreat gold ores. This chapter focuses on treatment methods for goldbearing ores.

  • A Brief Review of Pulp and Froth Rheology in Mineral Flotation

    In mineral flotation, rheological problems have the efficient upgrading of lowgrade and complex ores. Since pulp and froth rheology are deemed to play different roles in influencing the separation performance, in this paper, a brief review on pulp and froth rheology in flotation is provided, with an objective of developing a basic understanding of rheology in flotation.
