  • Recovery of iron from hazardous tailings using

    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 1060%, and the chief ferrous minerals in the tailings were hematite (Fe 2 O 3), magnetite (Fe 3 O 4) and carbonate (FeCO 3) (2)On an average global basis, iron ores tend to decrease in Fe grade over time With the exception for some deposits that are logistically challenged, iron ore resources in more accessible areas may often have processing issues, especially if highgrade concentrates are desired This paper addresses some of these with examples on how technological developments enhanced the feasibilityProcessing HighGrade Concentrates from
