| Abstract: | In iron ore, iron content of 32.54%, magnet content of 23.26%, silica content of 46.84%. The ores consist of a variety of minerals, and useful mineral fine granularity khenpos. In order to high efficiency and low energy consumption development and utilization of a microfine disseminated iron ore resoureces, Test was made on separating iorn by a process of discarding tailing at coarser size, stage grinding, staged low intensity magnetic separation and reverse flotation concentrate of magnetic concentrate. Obtained the following metallurgy index: iron concentrate assaying 65.13% Fe with iron recovery of 72.18%. |
