    The flotation method of concentration, used extensively for other metal ores, has only recently been utilized for hematite iron ores. It can be applied as either the sole concentration process or as a final concentration stage to ensure a high-grade product. In the flotation process, air is bubbled through a suspension of fine iron ore in water

    Jul 18, 2013 Concentration of iron oxides in gossan ore tailings (from cyanidation) by cationic froth flotation has been studied on a laboratory scale. About 50% of the iron content of the gossan ore tailings (45% iron, 22% silica) is recoverable as concentrate by a rougher flotation; 27% of the iron is in the middlings from the scavenger cells

    Aug 15, 2021 In phosphate ore concentration processes, amidoamines are more tolerant toward sulphate ions. They are also inexpensive and have fewer complications due to possible overdosage (Friedli, 1990). There are very few studies reporting the use of amidoamine molecules in iron ore flotation
