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.

Flash flotation an introduction AusIMM Bulletin

It is accepted industry practice that flotation rates are generally fastest in the ideal flotation size range, ie 20170 181m (Gaudin et al, 1931 Morris, 1952 Anthony et al, 1975). Below this size range, the flotation kinetics are generally slower due to, amongst other reasons, the streamlining effect of the particles and bubbles in a stirred system avoiding contact and bubble particle
