Braemar ore deposits are unusually soft and only slightly abrasive when compared to typical taconite or BIF deposits. The Braemar deposits therefore offer competitive grinding cost advantages. Braemar magnetite grains occur in a matrix of soft siltstone and shale and break readily along grain boundaries.

10%These investigations established that an addition of 200 g of CaO per metric ton of ore was the most effective in grinding quartz preferentially over magnetite at 75% solids concentration by weight. The limited rheological studies conducted suggest that the effect could either be due to dispersion or the structural modification of quartz.

A process for upgrading low-grade magnetite-containing iron ore with minimum fine grinding. The dry ore is first comminuted to between about three-fourths inch and 10 mesh particle size and magnetically separated. The dry tailing is discarded and the concentrate is ground to between about 20 and 100 mesh and again subjected to dry magnetic separation.

Magnetite is ferrimagnetic, which means it is attracted to a magnet. It is the most magnetic of all the naturally-occurring minerals on Earth. Naturally-magnetized pieces of magnetite, called lodestone, will attract small pieces of iron, which is how ancient peoples first discovered the property of >magnetism. Today it is mined as iron ore.
