Understanding microwave induced sorting of porphyry copper ores

All minerals were crushed to produce two size fractions (approximately 2000 μm and −74 μm). The coarser size fraction was tested as both separated grains and touching (heaped). Higher heating rates were reported when grains were touching, whilst slower microwave heating rates were measured for the finer size fraction.
