Organic compounds in the processing of lateritic bauxites to alumina Part 2: Effects of organics in the Bayer process

“…This concept is illustrated for a gibbsitic bauxite in Fig. 3, which is adapted from the data of Kotte (1981). The theoretical maximum yield, Y T , is then the product of the change in ratio, ΔA/TC, and TC:…”

“…Theoretical A/TC change under equilibrium conditions for a gibbsitic bauxite digested at 150°C followed by precipitation at 70°C (adapted fromKotte (1981)). …”
