IX. FROTH FLOTATION Froth flotation is a process used to separate minerals, suspended in liquids, by selectively attaching them to gas bubbles. Hence, in flotation we have a three-phase system. The separation principle is based on the lack of affinity of the mineral surface towards water, a property denoted by hydrophobicity.

Reverse Complement converts a DNA sequence into its reverse, complement, or reverse-complement counterpart. You may want to work with the reverse-complement of a sequence if it contains an ORF on the reverse strand. learn more 1 Froth Flotation Fundamental Principles

Abstract On Froth Flotation

Froth flotation as a fundamental method for processing complex minerals is commonly applied to the surface chemistry and beneficiation of rare-earth-bearing minerals. This is due to the fact that it is possible to process a wide range of fine particle sizes and the process can be tailored to the unique mineralogy of a given deposit.


The flotation plant design was based on extensive benchscale testwork including locked cycle tests on drill core and many months of operation of a 30 tonne per hour pilot plant using the old Cleveland Tin Mine process plant, modified for the duty.
