• Basic characteristics of Australian iron ore concentrate ...

     · The basic characteristics of Australian iron ore concentrate (OreA) and its effects on sinter properties during a highlimonite sintering process were studied using microsinter and sinter pot methods. The results show that the OreA exhibits good granulation properties, strong liquid flow capability, high bonding phase strength and crystal strength, but poor assimilability.
