Abstract

© 2019 Elsevier B.V. The property of lower soda and alumina contents of iron hydrogarnet can reduce the loss of soda and alumina in Bayer and Sub-molten salt process. Thus, the economic efficiency of alumina production could be improved. How to solve the effective formation of iron hydrogarnet in concentrated caustic aluminate solution and its cycle in the digestion process has become an important research topic. The base of hydroferrire desilication agents (calcium hydroferrite CHF, calcium hydroferrocarbonate CHFC, calcium hydroferrosulfate CHFS) were synthesized, the desilication experiments and desilication products (DSPs) were characterized, the results show that the hydroandradite and ..
