| 简介 |
A process for producing high grade blast furnace feed from poor grade iron ore ultra fines consists of processing ultra fines by selective dispersion to separate gangue materials from settled material iron and processing settled material of iron by re-dispersing with non-selective dispersant The dispersed settled material is then processed by selective flocculation with modified starch to separate concentrate iron for blast furnace feed from tailings leaving the gangue minerals in the dispersed phase. The process of separation between iron bearing minerals and the gangue minerals is carried out on the basis of surface charge conditions at a particular pH during re-dispersing with non-selective dispersant and segregating the finer particles by hydro-cyclone process for better flocculation to produce the final product that contains 68% Fe, 1% alumina and 1% silica. |
