Quarry fines, defined by the BS EN aggregate standards, are the inherent fraction of an aggregate passing 0.063 mm (63 microns). Many quarries also refer to their (sub-economic) fine aggregate (finer than 4 mm) as 'quarry fines' or 'quarry dust'. The term is used here to denote both fine aggregate and quarry fines.

As 20% of the total material stream turns into fines at the quarry, we expect fines for andesite and dacite to be readily available for purchase (Renforth, 2012). While these fines may be perfectly suitable for EW, their safe and effective collection and use for land application and ultimate weathering rates is an uncertainty in the supply chain.
