Iron ore tailings, which are important secondary resources, have outstanding latent application value in iron recovery. In this study, a pilot-scale experiment on the iron recovery from iron ore tailings was investigated using innovative technology of pre-concentration and suspension magnetization roasting (SMR), followed by magnetic separation and flotation.

Investigation of Adsorption Mechanism of Reagents (Surfactants) System and its Applicability in Iron Ore Flotation – An Overview July 2018 Colloids and Interface Science Communications 25(2):41-65

The rich iron ores normally are only comminuted and classified. The low-grade iron ore like Brazilian Itabirite have to be concentrated using gravity and magnetic concentration or flotation. Froth flotation is the most important concentration method, which is …

Starch exhibits excellent adsorption performance on hematite at a slightly alkaline pH. The flotation of hematite is depressed with dodecylamine acting as a collector, however, the flotation of quartz is minimally influenced. Thus, starch is commonly used to depress the flotation of iron minerals in the reverse flotation of hematite [6], [7].

China generates 1.5 tons of iron ore tailings for each ton of iron ore concentrate. 21,22 In this country, the annual production of iron ore tailings reaches about

Despite the recent success of the reverse anionic flotation of iron ores in the Anshan province in China, reverse cationic flotation remains the most popular flotation route used in the iron ore industry (Ma, 2012a). Comparing reverse anionic and cationic flotation is difficult because the processes are governed by the chemical, physical and ...
