Iron ore minerals are mainly silicate-type iron minerals in raw ore, and its distribution rate was 51.93%; followed by magnetic iron, and its distribution rate was 36.81%; content and distribution rate of other minerals was very low; element grade of iron, phosphorus, sulfur, silica were 11.90%, 0.043%, 0.013% and 45.23%, the main gangue were silica and calcium oxide, recyclable iron minerals mainly is magnetic iron mineral. Due to the grade of iron of raw ore and the amounts of optional magnetite was relatively little, in order to investigate the optional of low-grade ore, weak magnetic separation test and weak magnetic separation tailings-strong magnetic separation test were put into effect.

Process Characteristic

The composition of Deoxidized Samples of Bayan Obo Oxidized Iron Ore is complex with high content of residual reducing C, Fe phase in the RDP is ferrous metal what is hard and malleable resulting in pessimistic grindability. Gravity-magnetic separation process flow is adopted with C pre-rejecting, stage grinding (-0.074mm -57.18%, -0.074mm -85.66%) and coarse-fine fraction separate treatment base on RDP process characteristic. The final concentrate has 92.02% Fe with 93.27% Fe recovery, 94.18% Fe metallization which may utilize as rough materials for steelmaking and the final tailings has 15.10% REO with 97.15% REO recovery which may utilize as rough materials for REO concentration.

The mineralogy of slags of the Shuvakish ironworks plant is studied. The plant had been operated during the reign of Peter the Great from 1704 to 1716 years and was located within the present-day northwestern outskirts of Yekaterinburg. The slags are composed of fayalite aggregate with a signifcant content of hercynite and wustite and contain spherules of iron, glass, leucite and ferromerrillite. The chemical composition of rock-forming and ore minerals is determined on a JSM-6390LV (Jeol) SEM equipped with an INCA Energy 450 X-Max 80 EDS (Oxford Instruments) (Institute of Geology and Geochemistry UB RAS, Yekaterinburg). The slags formed as a result of bloomery iron production. Their formation temperature is estimated in a range of 1177 °С on the basis of eutectic crystallization of wustite and fayalite. The Shuvakish plant was supplied with marsh iron ore, which was most likely extracted in the nearest Moleben swamp located to the north from the plant.
