  • Minerals Special Issue : Iron Ore Flotation

    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

  • Investigation on alternative depressants for iron ore

    2010-10-1 · Brazilian concentrators employ cationic reverse flotation to concentrate iron ore fines below 105 μm. The commonly used reagents are corn starch and ether amine, respectively, depressant and frother/collector (Araujo et al., 2005). The use of depressant blends is not a common practice in Brazilian iron ore concentrators.

The reverse flotation route can be classified into reverse cationic flotation and reverse anionic flotation, based on the collector type. The

  • Interactive effect of minerals on complex ore flotation:

    Iron ore flotation is a complicated procedure. The presence of fine or ultrafine particles adversely affects iron ore flotation, which is probably due to the heterocoagulation and covering of fines. This process leads to variation in mineral surfaces, resulting in a low separation efficiency.

  • Recovery of Iron Ore Tailings byColumn Flotation

    The exploration of iron ore in small mining companies results in a large amount of unrecovered fine material, representing 35% of the run of mine. Millions of tons of useful minerals are discarded every year into tailings, incurring operation costs, raising production losses and environmental impact. In addition to the disposal of 300 t/h of this material, millions of tons are already stored
