Limestone Flotation using Oleic Acid Froth Flotation

Limestone Flotation Using Oleic Acid Froth Flotation

A direct flotation tends to take almost all of your impurities into froth just by entrainment. A separation is possible if you have a very dilute slurry, but this is commercially not viable. At the very high solid contents used in commercial limestone float operations, a direct flotation would result in mass transfer of all impurities as well into froth, just by mechanical entrainment.

Lime Use And Functionality In Sulphide Mineral Flotation

Nov 01, 2019 Flotation at high ionic strength has been reported to enhance the flotation of the inherent hydrophobic minerals (Haga et al., 2014), since the electrical double layer is compressed and attachment to the air bubbles enhanced (Lucay et al., 2015), and also finer bubbles are produced (Jeldres et al., 2016). Also, the flotation froth is more persistent and stable in the presence of dissolved salts.

Lime In Flotation And Recovery Processes Graymont

Lime is used extensively in the recovery of gold and silver. Ores, either run-of-mine, milled, autoclaved or roasted, are combined with lime and a cyanide solution. The cyanide dissolves the gold and silver. Lime maintains proper pH in the cyanide solution, keeping it in the liquid phase and preventing the formation of hydrogen cyanide gas and its loss into the atmosphere.
