iron ore tailing recovery rotary kiln

Recovery of iron from hazardous tailings using fluidized

Feb 01, 2020· The main chemical components of iron ore tailings in ANSTEEL were Fe and SiO 2. Hematite, magnetite, quartz and a small amount of chlorite were the major phases in the iron ore tailings. The total iron content reached 10.60%, and the chief ferrous minerals in the tailings were hematite (Fe 2 O 3), magnetite (Fe 3 O 4) and carbonate (FeCO 3). (2)

Re-beneficiation of iron ore tailings GoodRich MAGMA

Advantages of pelletisation Pellets are in high demand in the international markets, fetching a premium price, as they are ideal for blast furnace applications. When used in the rotary kiln, pellets reduce the iron ore requirement to 1.45 tons per ton of sponge, reduce the travelling time and increase the sponge output by 20-25%, reduce coal consumption by 15-20% and improve the metallization
