Potential low-grade iron ore deposits in

The low-grade iron ores in the Northern Province represent meta-banded iron formations (BIFs), with an average iron content of about 36%. The main iron-bearing mineral is magnetite. The Northern Province ores have to be milled to sizes smaller than 150 μm in order to liberate the iron minerals from the host rock, and beneficiation is accomplished through a series of magnetic separation processes.

Banded iron formation Wikipedia. Banded iron formations are almost exclusively Precambrian in age, with most deposits dating to the late Archean (2500-2800 Ma) with a secondary peak of deposition in the Orosirian period of the Paleoproterozoic (1850 Ma). Minor amounts were deposited in the early Archean and in the Neoproterozoic (750 Ma).
