  • Reagents in iron ores flotation ScienceDirect

    Different flotation routes are available: (i) reverse cationic flotation of quartz; (ii) direct anionic flotation of iron oxides; (iii) reverse anionic flotation of activated quartz. Most of this research took place in the USA during the decades of 1930 and 1940. Hanna Mining in association with Cyanamid developed the two anionic flotation routes, later employed industrially during the 1950s

  • Flotation of Iron Oxides and Quartz—A Review: Mineral

    12/11/2013· Froth flotation of iron oxides and quartz is reviewed over the broad range of particle sizes. The review, which embraces laboratory-, pilot plant- and industrial operations, encompasses (i) surface chemistry of iron oxides and quartz flotation (ii) relevant collectors and their adsorption mechanism and (iii) activation/depression in selective flotation, in this system.

    aLa présente recherche vise à améliorer la flottation sélective de quartz et de l'hématite en présence des sels d'alkylammonium en absence et en présence d'amidon de maïs. L'étude des propriétés structurales, morphologiques et superficielles des adsorbants révèlent que le quartz est très pur par rapport à l'hématite et que tous les deux ont de faibles surfaces spécifiques.

    Flotation Frothers What is the Function of Frothers. The function of frothers in flotation is that of building the froth which serves as the buoyant medium in the separation of the floatable from the non-floatable minerals. Frothers accomplish this by lowering the surface tension of the liquid which in turn permits air rising through the pulp to accumulate at the surface in bubble form.

INTRODUCTION The reverse cationic flotation is a conventional concentration process applied to iron ores. Quartz particles are collected in the froth after adsorption of ether amines, the iron oxides being depressed by starch. The removal of the fine quartz particles (< 0.150 mm) is

    The concentration of iron ore by flotation is a technique consolidated worldwide for mineral particles ranging from 10 to 250 μm [1]. In Brazil, all the main pellet-feed producers use re- verse flotation, being the tailing made up mostly of quartz and a concentrate constituted of iron oxides and iron hy- droxides. The most used reagents are amine and corn starch, which act respectively as
