Gravity Separation of Zinc Mine Tailing Using ... - SpringerLink

Roy and Das [ 9 ], in their study, separated hematite and goethite from kaolinite and quartz through dense media separation. They noticed that as smaller is the material granulometry, lower will be the contents of dense minerals, hematite, and goethite. The authors identified 68.47% of hematite and goethite for grain size 75-150 µm.
