INTERPRETATION OF FLOTATION DATA FOR THE DESIGN

Hellyer ore contains finely disseminated chalcopyrite, sphalerite, galena, and tetrahedrite. The flotation plant design was based on extensive benchscale testwork (including locked cycle tests) on drill core and many months of operation of a 30 tonne per hour “pilot plant” using the old Cleveland Tin Mine process plant, modified for the duty.
