Uwadiale (1990a) used selective oil agglomeration to upgrade Agbaja oolitic iron ore from a feed value of 45.6% Fe to a concentrate containing 65% Fe at 89.3% Fe recovery. The ore was very fine grained and ultrafine grinding (<5 µm) was required for liberation. The main iron mineral was goethite with minor hematite and maghemite.

Ultrafine Grinding an overview ScienceDirect Topics

At the forefront of these developments are two extremely different projects; the first is nano grinding of electronic materials and the second the ultra-fine grinding of ore bodies in the mining industry. For nano grinding, beads sizes of approximately 100 μm are required and potentially bead densities increasing beyond of 10 g/cc. For mining the environment is severe and beads must withstand high impacts from
