ANALYSIS OF THE DEPHOSPHORIZATION IN THE BOF AT ARCELORMITTAL TUBARÃO
Tecnologia em Metalurgia, Materiais e Mineração, 2013 Recently, the demand for steels with low phosphorus content has been increasing. Due to this, it is necessary to improve the process to attain higher phosphorus partitions in steels produced in the BOF. The present paper shows the modifications carried out in the process variables such as: flux additions and oxygen lance position, in order to achieve ...

Dephosphorization of Iron Ore through Bioleaching
, 2016 Phosphorus, as phosphate, is frequently found as a constituent of many of the world iron resources. Phosphorus is an extremely harmful element found in iron ore used as a raw material in the steelmaking process because it will affect the quality of iron and steel products.
