Bonaccordite is a rare mineral discovered in 1974. Its chemical formula is Ni2FeBO5 and it is a mineral of the ludwigite group. It usually crystallizes in long, cylindrical prisms that form within another source. It is named after the area of Bon Accord, where it was first found. There have also been findings of bonaccordite within nuclear plants at multiple companies. It builds up a deposit within the machines and is a very hard mineral to clean out because it is resistant to ordinary techniques.

==History== Bonaccordite was first described in 1974 for an occurrence in the Bon Accord area, Barberton, Transvaal, South Africa. It occurs in a tabular nickeliferous serpentinite, on the margin of an ultramafic intrusive. The actual site of the bonaccordite finding is a possible meteorite site three kilometers west of the Scotia talc mine.
