The ores were composed principally of iron pyrites (much decomposed), in a quartz matrix, with native gold in very irregular grains. Some portions, however, carried
DESCRIPTION: A flowsheet of Coarse gravity concentration followed by flotation circuit. ORE TREATED: On ores wherein base metals or gold bearing pyrite free at a
DESCRIPTION: Flotation of cyanide tailing after a Merrill-Crowe gold recovery circuit. ORE TREATED: Where ore bodies at depth have become more refractory and flotation ahead
DESCRIPTION: Flotation with cyanidation of flotation tailings. This flowsheet has a gravity gold recovery embedded into the grinding circuit’s ball mill discharge. ORE TREATED: Ores
DESCRIPTION: Flotation followed by cyanidation of flotation concentrates. In this flowsheet the flotation concentrates produced are reground and treated by cyanidation leaching. ORE TREATED: Sulphide
DESCRIPTION: Flotation followed by shaker table concentration in open circuit grinding. ORE TREATED: When the mineral in an ore is freed at a coarse mesh, this flowsheet
