Use of humic substances in froth flotation processes
(Academic Press, 2019)
Use of humic substances in froth flotation processes
(2019)
Continual growing demand for metals in regular and emerging markets has led to an increasing use of chemicals and reagents in ore processing. This trend force to incur in an increasing use of commodities which inevitable ...
Assessment of the floatability of chalcopyrite, molybdenite and pyrite using biosolids and their main components as collectors for greening the froth flotation of copper sulphide ores
(2014)
Biosolids and representative compounds of their main components – humic acids, sugars, and proteins – have been tested as possible environment-friendly collectors and frothers for the flotation of copper sulphide ores. The ...

Sistemas de reagentes surfatantes na flotação catiônica reversa de minério de ferro
(Universidade Federal de Minas GeraisUFMG, 2004-10-14)
Frother usage in cationic iron ore flotation still is scarcely employed in current applications and, consequently, the mechanisms involved directly on the synergic interaction between frother and cationic collector are not ...
Use of dispersants in flotation of molybdenite in seawater
(2017)
Molybdenite - as all inherently hydrophobic minerals – is floated with the use of water-insoluble oily collectors. Such collectors can be used in flotation either after emulsification in water, but can also be brought to ...
