Froth collapse in column flotation: a prevention

2005-4-1  Introduction. Froth collapse is a serious trouble in column flotation. Not only virtual sensors, which are also called soft sensing, but also expert systems have widely been used so as to solve such a problem. Both technologies are combined in this work to prevent froth overloading and the subsequent froth collapse.

2012-3-20  Ore ground at 50% solids used for flotation tests. Flotation tests were carried out with ultramafic Ni ores at 25% solids in a Denver cell using a dithiophosphate-based collector (40 g/t) and MIBC (20 g/t) frother for 12 minutes. Flotation tests were adjusted to pH levels ranging from 4 to 5.
