Investigation into the release of gravity-recoverable gold particles in products of a dynamic-impact mill

Abstract

The experimental data on assessment of the gravity-recoverable gold release in disintegration of lumpy gold-bearing geomaterials at dynamic-effect crushers DKD-300, designed at the Mineral Processing Laboratory at the Institute of Mining of the North, SB RAS, Yakutsk. The tests on gold-bearing ore originated from Gurbey deposit, made it possible to establish experimentally that the multiple-dynamic-effect facility enabled to release up to 47% gravity-recoverable gold of -1 mm in size.
