Done to process the low-grade oresFroth flotation was used for magnesite mineral processing as early as in 1930s by doerner and dwigh chen and tao 2004Single mineral flotation tests are widely used as a reference in flotation separation research to investigate the floatability of minerals for evaluating actual flotation processes.
Froth flotation a highly versatile method used to selectively separate hydrophobic from hydrophilic materials is a complex and poorly understood phenomenon; this process is difficult to robustly and optimally control because of its inherent chaos and upsets bergh and yianatos 2011The appearance of the froth surface in the flotation machine can be used as an effective.
Feb 06 2018 along with mechanized mining equipment froth flotation dramatically improved the efficiency of gold minesThanks to this process miners and refiners are able to extract quality minerals from ore at lower grades than has been previously possible – making it perhaps the most important mining industry innovation of the 20th century.

In mineral flotation rheological problems have limited the efficient upgrading of low-grade and complex oresSince pulp and froth rheology are deemed to play different roles in influencing the separation performance in this paper a brief review on pulp and froth rheology in flotation is provided with an objective of developing a basic understanding of rheology in flotation.
In this sense mining froth can be described as an aerated slurry that either occurs naturally or in some cases purposely created to assist with the separation of mineralsFroth flotation is an important step used for the recovery and upgrading of sulfide ores allowing far more economic recovery of valuable metals from much lower grade ore.
