The use of low-quality bauxites for alumina production results in the formation of a significant amount of technogenic waste—bauxite residue (BR). The Bayer reductive method is one possible way to eliminate BR stockpiling, but it requires high-pressure leaching at Low-Temperature Treatment of Boehmitic Bauxite Using the

Figure 11.2 models the refinery process flows at plant unit level (e.g. a bauxite mill is represented as a single unit). Units incurring high maintenance cost or exhibiting low reliability are indicated. The refinery can be thought of as a series of process functions operating on a circulating working fluid.According to Power and Loh (2010), the organic impurities in Bayer process liquor incur a cost of more than AU$ 500 million per year to the Australian alumina industry. 1.4.
