The Braemar | Magnetite Mines

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. In typical BIF and taconite deposits, the magnetite is inter-grown with a hard quartz-rich matrix and breakage is more often across grain boundaries.
