Flotation of water-soluble mineral resources ScienceDirect

Nov 19, 2004 The most efficient and selective method of saline minerals mechanical separation is by flotation. Potash ores were first processed in the 19th century by the hot leaching method, with further crystallization of potassium salts from saturated saline solutions. This method has been used to this day.

iron ore slimes [5]. When the test sample contains relatively lesser gangue, it is easier to float it and hence reverse flotation can be employed rather than direct flotation where in major proportion of the material, otherwise, would have to be floated. As such, the reverse flotation is the usual process for the beneficiation of iron ore slimes.
