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

This review is the second of a series examining the history and current state of knowledge of the science related to organic compounds in the Bayer process for the extraction of alumina from lateritic bauxites. The series of reviews provides a compilation of the information available from the public literature, and critical analysis of the research that has been carried out in this area in the past 50 years. It points the way to future opportunities for research to assist in mitigating the high costs that organics impose on the industry globally ($500 Mpa in Australia alone). Part 2 provides unique insights into the effects on the Bayer process of organic compounds in the liquor.
