  • The Role of Gravity and Intensive Cyanidation in

    A flow sheet has been developed to treat a high tonnage highly pregrobbing gold ore. The ore is low grade and fine grained with a high proportion of very fi ne free gold. The key components of the flow sheet include gravity flotation intensive cyanidation with direct electrowinning and carboninleach of the flotation concentrate.
