  True flotation versus entrainment in reverse cationic flotation …

  20181010 · The loss of iron-bearing minerals to the tailings, especially in the finest fractions (−44 μm), is a problem that must be endured due to the depletion of deposits containing high-Fe hematite. The two main mechanisms for iron mineral loss in the froth in reverse cationic flotation are hydrodynamic dragging and true flotation.

  Comparative studies of reverse cationic/anionic flotation of Vale iron ore

  2011914 · The comparative studies of reverse cationic/anionic flotation routes were conducted using Vale iron ore in batch scale flotation tests. The effect of slimes on the performance of the two flotation routes was also studied. After desliming, the overall Fe recovery in reverse anionic flotation is significantly higher than reverse cationic ...

  The Interaction between Iron Cyanide and Lead Ions in Pyrite Flotation

  2024527 · Despite being a major cyanide species in the process water, it is unclear how iron cyanide influences pyritic gold ore flotation as well as how lead ions influence pyritic gold ore flotation in the presence of iron cyanide. This study aims at revealing the interaction of Fe(CN)63− and lead ions in pyrite flotation to investigate the strong depressing effect of …

  Iron ore flotation with environmentally friendly reagents

  201451 · The Sydvaranger magnetite mine closed in 1996 due to low iron ore prices and was reopened in 2009. The flowsheet has remained more or less as in the old plant, based upon two grinding steps followed by magnetic separation. The magnetite is free of harmful elements and should be attractive on the high quality market. This requires a …
