Abstract
Compositions and methods used in the modification of crystallization of aluminum hydroxide from liquor in an aluminum hydroxide production process, such as the Bayer process. More particularly, crystal growth modifier compositions comprising a component of crude corn oil derived from a bioethanol production process and/or a component of biodiesel and methods of using such compositions to modify particle size and distribution of precipitated alumina trihydrate in a precipitation liquor crystallization process.
