Abstract
Ore characterisation is integral to any flowsheet development and equipment selection. There are risks to the overall flowsheet development if sufficient feed material is not characterised adequately representing the overall mine plan. The paper highlights some potential issues and opportunities to improve some of the commercial characterisations test procedures when macro-scale fractures, such as those apparent in RQD (Rock Quality Data); the response of friable ores with altered (argilic material) and remanent unaltered and hard / competent rock; and as well as variable rock shapes that make up the feed to a comminution circuits are considered.
