Abstract
During the long time,a large number of alumina plants were successful in economically increasing the productivity of the Bayer liquor loop.In recent years,the benchmark precipitation yield has increased from 70 g/l to 90+g/l,whilst producing sandy alumina.However with the theoretical maximum precipitation yield at 160 g/l there is still a wide gap to be closed.This paper provides an overview of past developments,the present status and the prospects,resulting from increased process knowledge and emerging technologies.It is envisaged that benchmark precipitation yield will soon cross the 100 g/l level.关键词
