— The final stage in iron ore processing is ironmaking, where the iron ore is transformed into molten iron through a process called reduction. The most common method of ironmaking is the blast furnace route. In a blast furnace, iron ore, coke (carbon), and fluxes (limestone or dolomite) are loaded into the furnace from the top.
2. Flotation routes for iron ore The flotation of iron ore was first investigated in America starting in 1931 (Iwasaki 1983, 1999; Uwadiale 1992).
— The flotation process is a separation technique primarily used in mineral processing for the recovery of minerals (Wills and Finch, 2016), that also finds application in other industrial processes such as wastewater treatment and paper recycling (Saththasivam et al., 2016, Vashisth et al., 2011).Separation of mineral particles by flotation takes …
