Minerals Special Issue : Iron Ore Flotation

12/05/2021  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 on iron ore concentrate value. The flotation ...

Reagents in iron ores flotation - ScienceDirect

The role of reagents utilised in iron ores flotation is reviewed. Desliming and flotation stages should be performed at pH levels as low as possible to reduce the expenses with caustic soda. Ether amines are by far the mostly utilised class of collector. The degree of neutralisation of the ether amine is an important process parameter. The partial substitution of amine by non-polar oils seems to be an attractive route.

Froth Flotation of Iron Ores - article.sapub.org

02/01/2012  The flotation routes of iron ore can be classified into five major groups, i.e. cationic flotation of iron oxide, cationic flotation of quartz, anionic flotation of iron oxide, anionic flotation of quartz, and combination[2]. Despite the variety of flotation routes developed for iron ores, currently, the reverse cationic flotation route developed by the USBM branch in Minnesota is by far the most widely used flotation route in the iron ore industry. The two anionic flotation ...
