Abstract
The article gives theoretical reasons and experimental results on gravitational and flotation concentration of fine gold from highly clayey geological alluvium deposits and placer mining wastes. It is proved that one of the promising ways to intensifying gravitational concentration techniques is the effectual preparation of the material for beneficiation. The authors show that flotation concentration of gold successfully contributes to gravitational concentration toward higher total output.
