2019-11-1  1. Introduction. Australia’s iron ore industry is undergoing a major transformation. Reserves of traditional high-grade ores are becoming depleted while the replacement ore types are lower in grade and sometimes require beneficiation to remove or minimise contaminants such as alumina, silica and phosphorus (Dukino et al., 2000).The phosphorus content of Australian iron ores is a particularly ...

Dephosphorization of High-Phosphorus Iron Ore Using ...

High-phosphorus iron ore is traditionally dephosphorized by chemical process with inorganic acids. However, this process is not recommended nowadays because of its high cost and consequent environmental pollution. With the current tendency for development of a low-cost and eco-friendly process, deph

Phosphorus in Steelmaking Processes SpringerLink

2018-5-26  This chapter examines the role of iron ore phosphorus in the development of steelmaking. The prosperity of steelmaking nations strongly depended on how they strategically dealt with iron ores with various phosphorus contents. At the beginning of steelmaking, the ore’s phosphorus content was immaterial. However, as the quality of steel ...
