In recent years the iron ore deposits have identified strong changes in the profile of ROM (Run of Mine) that feeds the processing plants. The relationship hematite/Itabirite (HE/IT) in ROMs, over time has become smaller ...

Since the Gol-Gohar iron ore mine (GGIOM), which is located in southeastern Iran, is currently one of the biggest iron mines in this region, increasing the accuracy of its mineral resources model has become a challenge for ...

A study was carried out into the use of charcoal as a supplementary fuel in the iron-ore sintering process. The primary fuel was coke breeze and anthracite with 0, 10, 25, 50 and 100% replacement of the energy input with ...

Several major iron deposits occur in the Quadrilatero Ferrifero (QF), southeastern region of Brazil, where metamorphosed and heterogeneously deformed banded iron formation (BIF) of the Caue Formation, regionally called ...

This paper presents the results of a study on carbothermal reduction of iron ore made under the microwave field in equipment specially developed for this purpose. The equipment allows the control of radiated and reflected ...

This work analyses pellets prepared with iron ore that has been mechanically activated by high energy ball milling. Pellet feed iron ore was submitted to high-energy ball milling for 60 minutes, and the resulting material ...

Iron ore is one of the important export products of Brazil. As only ore bodies with over 50% iron contents are mined, continuous efforts in prospecting are made. The use of Mössbauer spectroscopy as an aid to these efforts ...
