2018-3-15  1. Introduction. Froth flotation is one of the primary mineral processing approaches for separation and upgrading of valuable minerals from their ores (Fuerstenau et al., 2007, Nagaraj and Farinato, 2016).In froth flotation, a collector (a kind of surfactant) selectively attaches to a target mineral using its minerophilic group (Somasundaran and Wang, 2006), and then its hydrophobic group ...

2008-3-28  A flotation column is a reactor composed mainly of a collection zone and a froth zone. The collection zone has the objective of attaching hydrophobic particles to bubbles and the froth zone is responsible for the carrying capacity and froth enrichment (Finch and Dobby, 1990, Dobby and Finch, 1991).The drop-back material from the froth returns to the collection zone, goes back to froth, in ...
