Phosphorus Removal from Goethitic Iron Ore with a Low ...

Phosphorus associated with the goethite in high-phosphorus iron ores can be removed to 0.075% P using a heat treatment at 300–350°C for 1 h with 10 wt% NaOH, followed by a water leach. Heating at higher temperatures, up to 500°C, with heating times of 0.5 h to 4 h, gave no improvement in phosphorus removal.
