Minerals Special Issue Iron Ore Flotation

May 12, 2021 Iron ore flotation is a key technique to concentrate intermediate-low-grade ore, in order to reach the market requirements for higher-grade concentrates of iron. The presence of some impurities in addition to quartz in iron ore, aluminium silicates, and minerals containing phosphorus impair productivity in the steel industry and have an impact ... Learn More

Recovery of Iron Ore Tailings byColumn Flotation

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. Learn More

Investigations on different starches as depressants for

Aug 01, 2013 Reverse flotation of iron ore is now drawing more attention in iron ore industry as an efficient beneficiation process (Ma et al., 2011, Filippov et al., 2010, Araujo et al., 2005, Houot, 1983). In reverse cationic flotation, silica and silicates are floated after depressing the iron oxide by suitable reagents such as starch, dextrin, and CMC. Learn More
