Non magnetic physical separation of hematitic/goethitic iron ore
ROM ore is crushed in three stages to 90 mm nominal top size before rigorous washing and separation into five size fractions The two coarsest fractions −90 25 mm and −25 8 mm are gravity fed to the DMD plant with two separate Wemco drum sections Fig while the two middle fractions −8 5 mm and −5 2 mm are fed to the DMC plant with two separate
