The froth of a flotation column is usually . water washed, with approximately as much wash water as there is water reporting to the froth. The water is most commonly added via pans, perforated with 4-8 mm diameter holes, located 20-30 cm above the froth, thus generating a "rain" of water onto the surface of the froth.

A process is described for the mineral separation of rare earth metal compounds, such as bastnaesite, contained in oxidic minerals. The process is a froth flotation process utilizing a novel collector emulsion, which is an emulsified mixture of: a secondary amine modified sulphonated fatty acid, a high rosin containing tall oil fatty acid, an anionic petroleum sulphonate, and a high molecular ...
