Bayer process production of alumina hydrateThe alumina hydrate product is recovered in yields of about 80 g/l or more and the fine fraction constituting only a very minor fraction of the total alumina hydrate production is recycled after washing as seed to the first precipitation line for the production of additional alumina hydrate. The process, due to the relatively low temperatures utilized, may dispense with the use of interstage ...
