F
roth fl otation is used in many Australian coal handling and preparation plants (CHPP) for upgrading fi ne and
ultrafi ne coal. Although coal and sulphide ore fl otation are very diff erent, there are also some useful similarities. Here, we discuss some simple, cost-eff ective solutions that can be adopted in CHPPs to maximise fl otation equipment performance. T ere are some similarities between
coal fl otation and the cleaning stages in a sulphide concentrator – and the nature of concentrate (or product)
removal is also similar, with most of the mass in coal fl otation generally recovered in the fi rst 1-2 cells. Given these similarities between
coal fl otation and sulphide cleaners, there should also be benefi ts in sharing ideas to those in charge of monitoring and optimising these operations. Sulphide concentrators and
CHPPs have the following common objectives: highest possible yield (recovery) at the required product ash (concentrate grade); high equipment availability with minimal maintenance requirements; ability to handle high variability in loading and feed types
