| Abstract: | The principal components of iron minerals and gangue minerals in an iron mine in Guizhou were presented. The iron minerals were limonite and hematite, and the gangue minerals were alumosilicate such as clay and chlorite. There was fine disseminated size and complex associated relation in the iron mineral. It was easy to slime when grinding, therefore, it was difficult to beneficiate. A process was set forward: on the basis of orthogonal experiment of magnetizing roasting-low intensity magnetic separation, t... |
