Abstract
Dissociation of gold particles is tested in disintegration of Gurbey deposit ore samples under multiple impact effects in crusher DKD-300. It is found that in disintegration of gold-bearing schistose quartz ore, dissociation of gold particles larger than 100 μm in size extractable by gravity reaches 47%. The test results are confirmed by the data of the automated mineralogical analysis on scanning electron microscope TESCAN TIMA.
