DAF (Dissolved air flotation) is a procedure of induced flotation with very fine air bubble or « microbubbles », 40 to 70 microns.. Mechanical flotation is a term used in the mineral industry to describe the use of dispersed air to produce bubble that measure 0.2 to 2 mm in diameter.. The conditions for the appliion of the different flotation processes in water treatment are summarized in

Reverse flotation separation on diaspore and

The reverse flotation separation on diaspore and kaolinite can be carried out using collector dodecylamine acetate and depressant CPAM under pH5.58.5. On the surfaces of diaspore, there are a large amount of active aluminum atoms.

201548&ensp·&enspThe reverse flotation separation of kaolinite and diaspore has been achieved by using the collector dodecylamine (DDA) and depressant ionic polyacrylamide (CPAM) at pH 5.5–8.5. The flotation results have been explained by adsorption measurement, solution chemistry and density functional theory (DFT) calculations.

Abstract: The reverse flotation separation performance and mechanism of hematite and cellophane in the presence of RFP138, a newly synthesized dephosphorization collector, were studied. Reverse flotation tests on monominerals and artificially mixed minerals of hematite and collophanite show that, this anionic collector performs excellently in reducing the phosphorus content in hematite.

Reverse Flotation SURFI

Our collaborators from Northeastern University in Shenyang published a new paper on Reverse Flotation of Hematite from Quartz with Magnetic Seeding Aggregation in the Minerals Engineering journal. In this work, fine magnetite was used as a magnetic seed to enhance the separation efficiency of fine hematite from quartz during reverse microflotation.
