Method for purifying iron oxide - A/s, Sydvaranger

1992-9-8  One method for further purifying the iron oxide is to use the leaching method. It is known from the literature (cf. Bureau of Mines, Report of Investigation no. 7812) that the SiO 2 content in iron ore concentrate can be reduced to a significant degree by leaching in lye (NaOH solution).
