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 ...

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 ...

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 ...

Processes that produce less CO2 and less netr waste materials and emissions and that consume less energy are required. The international steel community is faced with the challenge of developing processes that will make ...

The aim of this work is to study MnO reduction by solid carbon. The influence of size of carbon particles, slag basicity, and bath temperature on MnO reduction was investigated. Fine Manganese ore particles were used as a ...

The aim of this work is to study the reaction rate and the morphology of the intermediary reaction products during reduction of iron ore, when iron ore and carbonaceous material are agglomerated together as a carbon composite ...

In Brazil, the main mining plants of Zn, in activity, are in the cities of Paracatu and Vazante, both in Minas Gerais. Zn contents in the ROM (Run of Mine) of the Vazante mine have been reducing over the years, in 2006 ...
