new bubbles produced in reactor/ aerator will be consider-
ably smaller than on top of the froth due to the bubble
coalescence.
Figure 5 displays that the pneumatic Imhoflot G-Cell
achieved a high-grade concentrate of 20.8 g/t (18.5–
22.5 g/t) at a recovery of recovery up to 66% (average
recovery of about 54.2%) from the average scavenger con-
centrate feed grade of 5.3 g/t Au with only two cells in
series.
Figure 6 displays the feed/ existing scavenger concen-
trate gold grade, pilot concentrate and tailings, recovery by
size and enrichment ratio. A high recovery of about 63.07%
was obtained for the fine particles (below 20 µm). From
the Au grade of 4.28 g/t, the Imhoflot concentrate contains
17.14 g/t Au with an enrichment ratio of 4.
