It is believed that certain reagent suites and in particular the addition of copper sulphate prior to collector addition could cause the chromite to be hydrophobic and hence amenable to true flotation (Wesseldijk et al. 1999).

Dec 12, 2005· Amine-aldehyde resins are disclosed for removing a wide variety of solids and/or ionic species from the liquids in which they are suspended and/or dissolved. These resins are especially useful as froth flotation depressants in the separation of bitumen from sand and/or clay or in the beneficiation of clay (e.g., kaolin clay) from an impure clay-containing ore.
