Beneficiation of a low-grade, hematite-magnetite ore

2014-5-1  In China, most reserves of rich iron ores have now been depleted and sustainable development of low-grade iron ores has become a critical discussion topic in the mining industry today. The aim of this study was to evaluate the applicability of beneficiating a low-grade, hematite-magnetite ore (assaying 18.64% Fe) for subsequent utilization.

Phosphorus Migration Behavior of Medium-Phosphorus

Time-dependent phosphorus migration characteristics during the carbothermic reduction process have been investigated based on the iron and phosphorus status in medium-phosphorus magnetite ore. The results show that the iron metallization enhanced from 84.38% to 96.49% with the reduction time varying from 10 min to 60 min.

Influence and mechanism of Indonesia vanadium titano

2017-12-29  Indonesia vanadium titano-magnetite (Indonesia VTM) mentioned here is a new iron ore which has a potential to be utilized in BF process. Basically, the element Fe, V and Ti can be economically utilized. In addition, the contents of harmful elements, e.g., S, P, and Zn are lower than permitted load of BF. For vanadium titano-magnetite in China, GAN et al maintained that the metallurgical properties of sinters got worse after adding vanadium titano-magnetite in mixed sintering materials in Panzhihua Iron and Steel Corporation, China, and lots of iron and slag could not get through coke layer into the hearth smoothly, which would make the permeability of BF become worse. DU et al pointed out that the key point of its application on BF was the fluidity of high TiO2 slag, and it would be not in favor of the smooth operation of BF process. Also, ZHOU et al stated that vanadium titano-magnetite
